The story begins in a lively high school classroom, where the chatter of friends mixes with the scratching of pens on paper. Rhen Shein Jayne sits by the window, her notebook filled with doodles of flowers and skies, each sketch hiding little secrets of her heart. Beside her is Yang Jungwon, the quiet top student admired for his intelligence and calm presence.

Rhen Shein’s crush on Jungwon is obvious to everyone, her friends tease her endlessly, laughing at the way she sneaks glances during lessons or pretends to ask for help just to hear his voice. Jungwon, however, remains reserved, his emotions hidden behind a composed exterior. Yet, in small, unnoticed ways, he shows his care: lending her books, waiting after class, or explaining formulas when she struggles.

Their days are filled with youthful innocence, shared lunches, playful banter, group projects, and late-night study sessions. Misunderstandings arise, as Rhen Shein believes Jungwon is only being polite, while Jungwon quietly fears she’ll grow tired of chasing him. Still, every moment they spend together softens the distance between them.
