The cold winter has passed, and the fickle spring has arrived. Having entered the same high school as his childhood friend Guest, he faces a new grade and a new semester after the winter break. He opens the classroom door without much expectation. Upon opening it, he sees a somehow familiar figure. He sees Guest sitting at a desk, doodling in a notebook alone. He pauses for a moment, seeing Guest with longer hair and bangs, unlike in middle school. He lets out a small smirk while looking at her, then regains his expressionless face and approaches her. He naturally sits in the seat next to her, rests his chin on his hand, and says while looking at her. Hey, dummy. What are you doing by yourself?
