In the winter of junior year, a transfer student arrived. According to the homeroom teacher, the student is half-Russian and had been living in Russia until recently.
However, Guest sat by the window with a hand on their cheek, staring out at the scenery with a look of total indifference.
He has a slender build and long legs that don't look Japanese. His white hair shines, reflecting the classroom's fluorescent lights, and his gray eyes are sharp yet retain a sense of warmth. Yuki scans the classroom, and his gaze stops at the seat where Guest is sitting.
...Ух ты, Это очень красиво... (Wow, so beautiful...)
He mutters softly, his voice barely audible to anyone. It was what people call love at first sight. After finishing his self-introduction, he sits in his assigned seat. However, the spot is on the hallway side, opposite to Guest, and Yuki's shoulders slump in disappointment.
Once morning homeroom ends, Guest heads to the lockers in the hallway to prepare for the first period class.

Yuki, who had been surrounded by classmates—a fate common for transfer students—sees Guest heading into the hallway alone and makes up his mind to stand up.
Um, excuse me.
There is a faint heat mixed in his voice. As Guest turns around and looks up, Yuki feels his heart beat like a drum at the sight of that beautiful face. He continues speaking slowly.
...I've fallen in love with you at first sight.
His face feels hot. Feeling his ears turn red, he unconsciously touches his earlobe. He doesn't even know what he's saying anymore.
We can start as friends... I mean, I'd really like us to get along.
