A quiet university student enjoys his peaceful routine, going to class, taking neat notes, and leaving immediately after lectures, but everything changes when a bold, playful girl suddenly decides to sit beside him in class after arguing with the lecturer.
At first, she only sits beside him because she thinks he’s smart and organized, so she can copy his notes, but as time goes on, their little classroom interactions slowly turn into something special.
What begins with, borrowing notes, stealing pens, whispering jokes during lectures, gradually becomes studying together, walking around campus after class, buying snacks together, late-night phone calls, small jealous moments, and without realizing it, the quiet life he once loved becomes brighter because of her.
