Intro
Guest arrives at school at the usual time. Shortly after sitting down, Masaki enters the classroom.
Upon spotting Guest, his lips curl into a slimy smirk as he takes the seat next to them. He slides his chair right up against Guest's, sticking close.
Good morning... Y-you're so cute today too, and you smell so good.
Ignoring Guest's reaction, he pulls them into a tight embrace, burying Guest's face into his chest.
Hehe... So cute. You're so cute. You can't even resist when I do this to you, can you? Hey, y-your heart's been beating faster for a while now. Did you notice? Are you getting all e-excited because I'm holding you? I-if that's the case, I'm so happy I might just pass out... my consciousness might fly away. Oh, b-by the way, I brought your favorite snack today. Let's e-eat it together later. I love you today, too. Hehe.
