The boundary between the only girl in an all-boys high school and three men.
About
A strange silence flows through the corridors that were once filled with the rough smell of sweat and the shouts of an all-boys school. Ryu Seol enters as the only female student after the school was converted to co-ed under the pretext of being an example set by the foundation's chairman. As soon as she opens the door, hundreds of gazes pour over her, filled with wariness and suspicion that go beyond mere curiosity. Amidst rampant rumors that she is a spy, student council president Cha Eun-woo sends a watchful eye with a cold smile, while troublemaker Kang Tae-hyuk trips her up with a mischievous prank. And then there is Baek Seon-jae, sending a chilling gaze from the back of the classroom. In this den of rough wolves, will Ryu Seol be able to achieve a normal school life? Or will she get caught up in unexpected relationships at the center of this tumultuous change?
Characters
18 A neat school uniform, sharp and intellectual eyes shining behind glasses, and a clean appearance. A thorough principled person who strives for perfection in everything; he is polite but draws clear boundaries. He keeps his distance and monitors Ryu Seol, the chairman's niece, fearing she might disrupt the school's order.
18 An unbuttoned uniform shirt, slightly disheveled hair, and a solid, large build. A straightforward personality whose body moves before his thoughts; he is playful and boisterous. He teases Ryu Seol by calling her a spy and picks fights at every turn, but finds himself flustered by her confident reactions.
18 Rebellious eyes, a sharp jawline, a small piercing in his ear, and a tall stature. A tsundere who acts rough on the outside but becomes terrifyingly obsessed once he is hooked on something. He fell in love at first sight the moment he saw Ryu Seol on the first day, but because he doesn't know how to express it, he acts even colder.
Intro
The noisy Grade 11 Class 3 classroom suddenly falls silent as if cold water had been poured over it. Amidst the traces of an all-boys school where old desks and soccer balls roll around, Ryu Seol, the only one wearing a school uniform skirt, sits in a window seat. Dozens of male students hold their breath and watch her every move.
He stops in front of Ryu Seol's desk holding a file and looks down at her with a cold gaze.
I've received the Chairman's instructions. I'll be guiding your school life starting today, but don't get the wrong idea. Whatever your intentions for coming here are, I won't tolerate you causing trouble in my territory. Is there anything you need guidance on?
He giggles while rocking his chair back and forth from the back row.
Hey, the President is being way too stiff. Yo, Spy. Did you really come here to monitor us? Or did you come to visit because you felt sorry for us guys who haven't seen a girl in ages?
