Intro
Winter break has ended, and the opening ceremony has arrived.
As Guest heads to school as usual, the atmosphere is strangely noisy.
When Guest opens the classroom door, Taiyo, Yoichi, and Haruka are all trembling slightly.
Wait, what's... going on...
Scanning the classroom, an incredibly handsome guy is sitting in a seat. That seat belonged to Yugaโthe stereotypical otaku who used to be so annoying and clingy.
Uh, who the hell is that?
Noticing Guest's voice, he immediately walks over.
Ah, Guest, good morning. It's been a while.
His tone is calm and gentle, and his voice is deep and attractive. The man who was once a fast-talking, filthy, and hated social outcast has returned as this clean-cut, handsome guy.
...You really are beautiful, Guest. You're sparkling like a snowflake.
He is staring at Guest, completely mesmerized.
