Maru Is A Puppy Chapter 11-20: To A Kindergarten

Maru Is A Puppy Chapter 11: Power Outage

Maru Is A Puppy Chapter 11 begins with Maru and Seoyul following bubbles and discovering two older girls playing with bubble blowers. Maru’s incredible speed at popping the bubbles surprises the girls. One of them runs forward, asking them to stay, and soon returns with a bubble gun. Excited, Maru enthusiastically pops the bubbles, with Seoyul helping her too. The four children become friends and play together among the flowers. After a fun time, Maru and Seoyul say goodbye to the older girls before heading toward Woori and Junho, unaware of their little adventure.

Later that night, Woori is busy with her work, but Maru wants to play. Woori promises to play after she finishes, leaving Maru upset. Suddenly, she notices a crow by the window and scares it off. In an act of apparent revenge, the crow pulls on a nearby power line, causing a sudden outage. Just as Woori is about to save her work, the lights go out. Junho then arrives with Seoyul, curious if they’ve lost power as well.  He is surprised when he finds Woori crying with a blank expression. Just then, he hears another set of footsteps behind him, and Maru Is A Puppy Chapter 11 ends with the door slowly creaking open.

Chapter 12: Minefield

Maru Is A Puppy Chapter 12 opens with Sunjeong entering the room, her face mirroring her fear, which in turn scares both Junho and Seoyul. This reaction causes Sunjeong to jump back, resulting in a chaotic atmosphere. Meanwhile, Woori remains lost in her sadness over her unsaved work. Junho explains that the neighborhood is experiencing a power outage and urges the adults to stop crying. He expresses a desire to leave with Seoyul, but Sunjeong pleads with him to stay, reminding him that his phone is the only one with a flashlight since neither Woori nor Sunjeong has charged their devices. Reluctantly, Junho agrees to stay for Seoyul.

Sunjeong attempts to comfort Seoyul, but instead ends up scaring him further. Maru steps in to reassure her friend and introduces Sunjeong as her boss. Meanwhile, the adults wonder when the lights will return but grow bored waiting in the dark. To cope with the silence, they decide to play shadow puppets. After their show, Maru retrieves her toys and suggests playing a game to see how high they can stack blocks. Woori beams at Maru’s ability to care for them all.

However, disaster strikes when Sunjeong accidentally knocks the blocks out of the box, and at that moment, Junho’s phone flashlight turns off. Seoyul and Sunjeong burst into tears now that it is dark, while Woori feels perplexed about how to clean up the scattered blocks. Maru Is A Puppy Chapter 12 concludes with Maru navigating through the darkness, leading the way to Seoyul, holding his hand.

Maru Is A Puppy Chapter 13: Middle School Friend Visits

Maru Is A Puppy Chapter 13 begins with Maru guiding Seoyul through the darkness towards Sunjeong, who is crying. Sunjeong grabs Seoyul’s hand, and they both start to calm down. Junho checks on Seoyul, who assures him he’s okay. Woori informs them that Maru can see in the dark, prompting Junho to suggest Maru should help clean up. However, Maru playfully pinches Junho, which annoys him.

Just then, the lights suddenly return, and everyone feels relieved. Both Junho and Woori notice Sunjeong and Seoyul holding hands, but Junho grows annoyed at Maru for playing instead of helping with the blocks. With the lights back on, they decide to leave, and Seoyul acknowledges that Sunjeong is the boss. Woori enjoys the time spent with her friends until she notices numerous missed calls and messages from someone named Mahui, which leaves her devastated once again.

The next morning, Maru asks Woori if she will buy her new toys. Woori realizes her expenses have increased now that Maru is human but feels happy nonetheless, surprised that no one has discovered her secret.

In the following scene, we’re introduced to Mahui, who is livestreaming her journey to her editor friend’s house, bringing along pet supplies for her friend’s cute dog. Meanwhile, Maru senses someone approaching the door. Mahui inquires about Woori’s whereabouts from a neighbor, learning that Woori has a little sister. Shocked, she rushes to Woori’s apartment and bangs on the door. Woori, seeing Mahui through the peephole, feels tense. Maru Is A Puppy Chapter 13 concludes with her panicking as Maru opens the door to greet Mahui.

Chapter 14: Upset

Maru Is A Puppy Chapter 14 opens with Mahui expecting to see Maru the dog but is taken aback to find Maru as a human. With a deadpan expression, she asks Woori if she doesn’t have a little sister but rather an older sister. Maru claims to be Woori’s little sister, which leads to an argument between the two. Woori suddenly interjects, stating that Maru is her little cousin.

Suspicious, Mahui asks where Maru’s parents are. Woori quickly fabricates a story, saying Maru’s parents are in the hospital long-term and that Maru will be staying with her while she works from home. Mahui accepts this explanation but then asks for Maru’s name, causing Woori to panic again. Maru confidently declares her name is Maru, but this only raises more suspicion from Mahui.

Feeling defeated, Woori stammers that she must have named her dog after her cousin. Mahui expresses disappointment since she had bought goodies for Maru the dog, but now Maru is rebuked from touching them. Mahui inquires about Woori’s dog, and Woori tells her it is now living with her parents. She suggests sending the goodies to Woori’s parents, disappointing Maru, who tears up, fearing Mahui now dislikes her.

Woori reassures her as Maru howls and cries on her bed. Mahui is puzzled by Maru’s tears, and Woori blames her for saying Maru is not the “real” Maru. Worried about the situation, Woori suddenly comes up with an idea: they should dine out together. Maru Is A Puppy Chapter 14 concludes with the three of them leaving for the restaurant, while Maru feels upset that Mahui does not remember her.

Maru Is A Puppy Chapter 15: Trouble At The Diner

Maru Is A Puppy Chapter 15 opens with Woori, Mahui, and Maru stepping outside to dine at a restaurant. They unexpectedly encounter Junho, who tries to reach out to Maru but is met with a brutal rejection. As they settle into the restaurant, the friends attempt to cheer Maru up, but their efforts fall flat, and her mood darkens. Feeling guilty, Mahui invites Maru to sit next to her. After a moment of contemplation, Maru chooses to sit next to Woori instead, leaving Mahui embarrassed. Woori takes charge, attempting to ease the tension by ordering food, and they find some relief when Maru begins to eat.

However, Mahui offers Maru some food, and Maru spits it out, so the relief is short-lived. Upset, Mahui accuses Maru of not liking her, and Woori tries to comfort her, but Mahui retorts that she doesn’t like Maru either, leaving Maru shocked. The escalating situation perplexes Woori just as a group of Mahui’s fans approaches, asking for a photo. Although Mahui politely declines, a commotion ensues as more people crowd around her, snapping pictures. Sensing Mahui’s distress, Maru unexpectedly rushes forward, grabbing a guy’s phone in her mouth and taking off. Woori stands stunned while Mahui watches, feeling amazed and reminiscent of Maru the dog. Maru Is A Puppy Chapter 15 concludes with Maru, phone clenched in her mouth, looking decidedly angry.

Chapter 16: Reconciled

Maru Is A Puppy Chapter 16 begins with people expressing their frustration after Maru has taken their phones. They grow angry, but Maru retaliates, insisting that Mahui doesn’t want her photo taken. Shocked by her outburst, Woori pleads with Maru to return the phones. After a brief pause, Maru refuses and runs off. Amid the chaos, Woori manages to retrieve the phones and returns them to the crowd. Mahui, reflecting on the incident, realizes that Maru was simply throwing a tantrum rather than hating her.

Curious, Mahui asks Maru if she likes her, to which Maru unknowingly responds with a yes. Surprised, Mahui excitedly declares her love for Maru. They return to their table, and Mahui encourages Maru to order anything she desires. Although Woori worries about wasting food, Mahui reassures her that nothing will go to waste as they prepare to eat. It’s then revealed that Ha Mahui is a famous Mukbang YouTuber. Maru is impressed by Mahui’s eating skills, and they bond over the meal, solidifying their new friendship. Woori feels relieved that everything has been resolved.

In the next scene, Woori scolds Mahui for buying too many toys for Maru, but Mahui seems unfazed. This leads to a filler episode where Woori, Maru, and Seoyul dress up as a dynamic duo called Ru and Yul, with Junho cheering them on as the sole audience member. They enjoy themselves, and even Junho gets an outfit. Maru expresses her desire to ride a pogo stick, and Seoyul suggests she can play with him and his friends at the park. Woori grows worried for Maru, and Maru Is A Puppy Chapter 16 ends with Maru about to meet Seoyul’s friends at the park.

Maru Is A Puppy Chapter 17: Treasure Hunt

Maru Is A Puppy Chapter 17 begins with a girl asking Maru how old she is. Woori responds that Maru is five, to which the girl immediately retorts that she is six. The girl, introducing herself as Yoojin, asks Seoyul why he brought a little kid along. She instructs Maru to call her “big sis” Yoojin, but Maru simply addresses her as Yoojin, which annoys her.

Yoojin explains that they are trying to solve a riddle and urges Maru to leave. Although the other kids want Maru to join them, Yoojin is not interested. Instead, she focuses on finding treasure in the playground. Excited by the idea of a treasure hunt, Maru expresses her desire to join, and Yoojin reluctantly agrees, eager to solve the riddles herself.

Yoojin solves the first riddle and reveals that the second one is located on a slide. She is surprised to see Maru slide down so easily but warns her that the third riddle is about a sphinx. The third riddle instructs them to find the color once they ride the sphinx. However, the children struggle to decipher it. Maru climbs onto the sphinx in search of the clue but ends up getting distracted. As she quickly rides the sphinx, she suddenly spots the color purple. Understanding the assignment, she races over to the purple foam blocks.

Everyone is shocked when Maru discovers the next riddle, and a boy remarks that one sees purple only when going very fast. They all applaud Maru for her success, and together they move on to the next riddle. Maru Is A Puppy Chapter 17 concludes with the new riddle stating, “It goes up if you gather, down if you disperse; you must fly to see the next path.”

Chapter 18: Curious Adventurers

Maru Is A Puppy Chapter 18 begins with Seoyul and Yoojin deducing that the answer to the riddle is a see-saw. The kids place Maru on one side while they sit on the other, sending her up into the air. Yoojin asks if she sees anything, and Maru waves excitedly at Woori, becoming distracted once again. Frustrated by Maru’s lack of focus, Yoojin watches as she accidentally slips down. The other children gasp, and Woori rushes to help, but Maru manages to hang on to the see-saw, ultimately discovering the final clue hidden underneath it.

Following the instructions of the last riddle, the group takes ten steps forward along the orange path, but they feel disappointed to find no treasure. Yoojin begins to sulk, but Maru suddenly has an epiphany. As Yoojin turns to leave, Maru stops her. Just then, water erupts from underneath, showering them all. Seoyul excitedly realizes this is the treasure they are seeking. The kids cheer and start playing with the water, and it seems Maru has made new friends.

Curious about Maru’s background, Yoojin asks which kindergarten she attends. Maru Is A Puppy Chapter 18 concludes with Maru telling Woori that she wants to go to kindergarten.

Maru Is A Puppy Chapter 19: Errand

Maru Is A Puppy Chapter 19 begins with Woori feeling anxious about the idea of Maru attending kindergarten. When Woori realizes she is out of soy sauce, Maru volunteers to fetch some. Although Woori feels slightly worried, she hopes that this errand will help Maru focus. She advises Maru to go downstairs for the soy sauce and warns her not to go outside. Maru listens lightheartedly and runs off, increasing Woori’s concern. Following closely behind, Woori calls Junho to inform him that Maru will be coming by for the soy sauce.

An old man greets Maru, who unexpectedly rings the doorbell of the wrong apartment, and gives her candy. Forgetting her original errand, Maru decides to head back when she encounters Sunjeong. Woori believes Sunjeong can assist Maru with her task, but she ultimately sees Sunjeong as no better than Maru. Sunjeong asks where Maru is going, and Maru responds that she is headed to the “juice’s house,” as Junho helps her with juice boxes.

Meanwhile, Junho waits for Maru’s arrival. Sunjeong questions Maru about this “juice,” leading Maru to make a humorous impression of Junho. Understanding her confusion, Sunjeong rings Junho’s doorbell for Maru. As soon as Junho opens the door, he asks what she wants. In a moment of excitement, Maru asks for soy sauce as if she were in a grocery store. Junho lends her the soy sauce, and Maru, in return, gives him her candy, making Junho smile.

Maru returns with the soy sauce, looking proud of her accomplishment, and Woori praises her. She then asks if she can go to kindergarten, leaving Woori to ponder the decision. Maru Is A Puppy Chapter 19 concludes with Maru preparing for her first day at kindergarten.

Chapter 20: First Day At Kindergarten

Maru Is A Puppy Chapter 20 begins with Woori feeling anxious about Maru’s first day at kindergarten. The scene shifts to another teacher, Dahye, who is showing a picture of her dog to Sunjeong. Sunjeong mentions that Maru, her neighbor, will be joining the class. When the students arrive, Dahye greets Maru and is taken aback by how much she resembles a dog.

In the next scene, Dahye considers the possibility that she might be imagining things and decides to pay extra attention to Maru to help her adjust. She introduces Maru to some children who are playing house, and the children choose Maru to play the puppy. She immerses herself in the role, delighting the other kids and leaving Dahye astonished.

Later, the kids go outside to play in the playground, where Sunjeong asks Dahye about her day. Dahye inquires whether Sunjeong notices anything different about Maru. Surprised that Dahye has picked up on it too, Sunjeong points out that Maru is the only child unafraid of her. Another teacher compliments Maru, noting she is very brave and a fast runner. As they watch the children play, Dahye is further shocked to see Maru acting like a dog and wonders why the others seem oblivious to this.

Sunjeong then asks about a student named Tan, prompting Dahye to go check on him. Meanwhile, Maru pauses, sniffing the air, and suddenly looks up at a tree. Maru Is A Puppy Chapter 20 concludes with a boy sitting on a branch, looking down at Maru.
