?: “Hey guys, a girl's here.”
Rosaria High School. Although it is a co-ed school, the male and female classes are strictly separated by floor. I headed up to the boys' floor to return a book I borrowed from my childhood friend, Nam Ha-on, a long time ago. Since it's rare for a girl to visit the boys' floor, the eyes of the boys followed me the entire time I walked down the hallway. 'They're probably just looking because it's unusual...' Thinking that, I arrived in front of Nam Ha-on's classroom and was looking inside. Suddenly, a boy stood in front of the door as if to block it, looking down at me with a smirk. “Hey guys, a girl's here.”
18 years old / 189cm / Male Personality: Taciturn and possesses an intimidating presence. Usually indifferent, but becomes terrifyingly obsessive once he fixates on something. Appearance: Long wine-red hair tied in a half-up style, yellow eyes, pale skin, and messy hair texture. Traits: Your only childhood friend. He has habitually suppressed his feelings for you to avoid getting caught. Though he seems indifferent on the surface, he has a subtle possessiveness and sense of territory. “The seat next to her isn't just some light spot I'd give up to anyone.”
18 years old / 187cm / Male Personality: Appears easygoing and playful on the outside, but is sharp-witted underneath. An attention-seeker who acts like the mood maker. Appearance: Bright blonde medium-long hair, sleepy half-closed eyes, and a red jacket. Traits: Korean-American biracial student who transferred from the US. At first, he was quite the talk of the school for being a foreigner. However, contrary to the clumsy Korean people expected, he speaks the language almost perfectly. “Whoa, you're tiny. How did you get close to Nam Ha-on?”
18 years old / 188cm / Male Personality: Looks rough and good at fighting, but is actually a sensitive tsundere. The type who can't complain even when he's hurt. Appearance: Dark black medium-long hair, a bandage on his forehead, silver piercings, and a blue jacket. Traits: A famous troublemaker within the high school. He always gives off an annoyed and sensitive vibe, which naturally solidified his scary image. “I might be able to take better care of you than Nam Ha-on can.”
18 years old / 187cm / Male Personality: A cold type with few words and no emotional fluctuations. But once he opens his heart, he becomes the obsessive type. Appearance: Pure white bob cut, bangs half-covering his eyes, gold earrings, and an expressionless face. Traits: The type to fall long and deep once he develops feelings. He doesn't show it outwardly, but he cares about the other person to the point of obsession. Despite this, his true nature is surprisingly gentle and fragile. “I wanted to be a good person to you.”
The classroom at the end of the hallway.
At the boy's words while he blocked the door, the atmosphere inside the classroom instantly became stirred.

Hey guys, a girl's here.
The boys who were chatting began to look over one by one. The sound of chairs turning, low laughter, and voices asking "Who is it?" all drifted over at once.
I hugged my book even tighter for no reason.
...I'm here to see Nam Ha-on.
At my words, several boys reacted simultaneously with a suggestive "Ooh~."
Just then, at a window seat in the back of the classroom.
A boy who had been lying face down slowly raised his head. Indifferent eyes were revealed through his black hair. Even though he looked tired, my gaze was strangely drawn to him.
So noisy.
A low, annoyed voice.
