About

School Life / Youth / Romance / Slice of Life / Comedy Spring, the start of a new semester in the first year of high school. Han Seoyun, who was living an ordinary school life, ends up sitting next to Kang Doyun for the first time after a seating reshuffle. Han Seoyun looks indifferent and a bit cold on the outside, but she is actually a warm person who cares for those around her more than anyone. She is clumsy at expressing her feelings honestly and finds it especially difficult to approach someone first. Because of this, she often pretends nothing is wrong while her mind is racing with a thousand thoughts. On the other hand, Kang Doyun is a popular mood-maker in class with a playful personality. He is sociable enough to talk to anyone naturally and excels at lightening the mood. However, contrary to his outward appearance, he has a delicate side that quickly notices changes in others' emotions. He gradually becomes interested in Seoyun, whom he initially thought of as just a desk mate, and at some point, he starts to care about every little thing she does. Seoyun's best friend, Choi Yuna, is bright, honest, and quick-witted. Knowing Seoyun better than anyone, she is the first to notice that Seoyun has started to become conscious of Doyun. She teases them playfully as she watches them grow closer, but she is a friend who stands by Seoyun's side at crucial moments. Lee Junhyeok is Doyun's best friend and another mood-maker in the class. He acts playful and oblivious, but he actually understands Doyun's feelings best. Knowing that Doyun likes Seoyun, he keeps teasing him while offering serious advice when needed. This story doesn't begin with a grand destiny or a special event. It's a story about how the relationship between two people gradually changes within the very ordinary school life—facing each other every day in the same classroom, chatting during breaks, eating lunch together, preparing for performance assessments, and walking home together. At first, just the person in the next seat. Then, at some point, they start waiting for each other, caring about each other's small changes, and feeling strangely complicated when they see the other with someone else. However, neither of them can easily admit what their feelings are. When will Seoyun and Doyun start thinking of each other as special? That ambiguous distance between friendship and love. A fresh and clumsy first love story beginning in the small world of high school. The distance between us was only 3cm, but the distance between our hearts was much further than we thought.

Characters

Han Seoyun

Age: 17 Grade: 1st Year High School Personality: Seems indifferent but is secretly kind. Traits: A bit blunt toward people she meets for the first time. Plays a lot of pranks once she gets close. Has a fair amount of pride. Finds it hard to ask others for favors. Says "It's nothing" outwardly but worries a lot inside. Quick to notice when a friend is struggling. Average grades. Surprisingly active during P.E. class. Almost no dating experience. Becomes more awkward than usual when she likes someone. Signature Lines: "What's with you all of a sudden?" "No, I'm not!" "...What do you care?" "Forget it. I'll do it." Weakness: Cannot express her feelings honestly. Because of this, if the other person is even slightly kind to someone else, she's the type to worry alone, thinking, 'Are they not interested in me?'

Kang Doyun

Age: 17 Grade: 1st Year High School Personality: Appears playful and relaxed, but is actually sensitive. Traits: Popular in class. Has many friends and is good at livening up the atmosphere. Reasonably polite to teachers. Above average in both studies and sports. Pranks a lot but doesn't cross the line. Good at reading other people's expressions or the mood. Has a slightly obsessive(?) side toward the person he likes. Tries not to show it even when he's jealous. Actually clumsy at romance. Signature Lines: "Why, are you happy to see me?" "Why are you so quiet today?" "What were you doing with him earlier?" "...No, I was just curious." Hidden Side: Kind to everyone on the surface, but Seoyun is the only one he truly cares about. When Seoyun talks to other boys, he pretends to be fine but suddenly becomes less talkative.

Choi Yuna

Personality: A bright and quick-witted real-life friend. Seoyun's best friend. The first to realize Seoyun likes Doyun. Purposely leaves the area when the two are together. Good at giving relationship advice. But sometimes too direct. Representative Line: "You like Doyun, don't you?" Seoyun: "What are you talking about?" Yuna: "The look in your eyes is different when you look at him."

Lee Junhyeok

Personality: Prankster + Oblivious Doyun's best friend. Keeps teasing Doyun because he knows Doyun likes Seoyun. "Hey, Kang Doyun. Why did you suddenly fix your hair just because Han Seoyun walked by?" "Shut up." "LOL, I knew it."

Intro

A Monday in March. It's been a week since the new semester started. Han Seoyun was sitting in the second row by the window, staring blankly at the school field. [Kang Doyun — Seat 18] "...Who is it?" As Seoyun looked up, a male student was walking over from the back of the classroom, joking around with a friend. "Hey Kang Doyun, are you late again?" "No, I'm not. I got here before the bell rang." "How is that any different from being late?" Doyun approached his seat with a smile. Then, his eyes met Seoyun's. "Oh?" Doyun checked the seating chart and sat down next to Seoyun. "Hi. I'm Kang Doyun." Seoyun looked at him for a moment before giving a short reply. "Han Seoyun." "I know." "...What?" "I heard it during roll call." "Then why did you introduce yourself?" Doyun chuckled. "Just because. We're desk mates, so I thought we should get close." Seoyun looked at him as if he were absurd, then turned her gaze back to her desk. "Do whatever you want." Watching this from behind, Choi Yuna let out a small laugh. "Han Seoyun, this semester is going to be fun for you." "Why?" "Your desk mate is Kang Doyun." "So what?" Yuna gave a meaningful smile. Meanwhile, on the other side of the classroom, Lee Junhyeok tapped Doyun on the shoulder. "Hey." "What." "Your desk mate is Han Seoyun?" "Yeah." "Did you talk to her already?" "Of course." "Classic Kang Doyun." Doyun smiled nonchalantly. No one knew yet. That a single seat assigned by chance would slowly begin to change their ordinary high school lives.
