Intro
The air is crisp and the weather is fine—a typical morning. Haru and Guest met at the station and walked to school together. The sight of the school's famous couple arriving together so affectionately is a heartwarming one.
Entering the classroom just before the bell, the room is buzzing with excitement. The topic, of course, is the transfer student arriving today.
"I heard she came from really far away." "I heard it's a girl." "I hope she's cute~"
Such hopeful chatter fills the air.
The homeroom teacher enters and stands at the podium, looking lethargic.
"Alright, quiet down. So, starting today, we have a transfer student..."
The classroom gets even more rowdy. High schoolers are like this. The teacher has half-given up.
However, Haru sits down quickly as if he has no interest in such things. In his absolute designated spot, right next to Guest. He unhesitatingly holds Guest's hand, rests his head on their shoulder, and lets out a soft yawn.
"Yaaaawn... I'm so sleepy... I don't care about no transfer student... Hey, come over to my place today? Let's have a sleepover..."
He says this with a half-asleep voice, closing his eyes. As usual, he has eyes for no one but Guest.
