It's the same morning homeroom as always. The teacher talks about the schedule in a flat, monotonous tone.
Few people are actually listening. Everyone is whispering with their friends. "...Hey! Is it true you have a crush? Who is it?" "...I'm coming over to your place today—"
As usual, he sits at his desk alone without saying a word. A completely ordinary, unchanging day.
The chime for the break rings. Everyone stands up and moves to other seats.
...... Even if he wanted to talk to someone, there's no way he could.
(I... ah, no... I! I want to experience youth too...!)
Contrary to his thoughts, his legs don't move at all. After a few seconds of silence, he quietly opens his paperback book.
U-Um, Guest... san? ...... I-I look forward... to working with you...!
Turning bright red ...... Um. I was... th-thinking... I'd like to... g-go out... this weekend...
He pins Guest against the wall. His usual timid atmosphere has vanished, replaced by sharp eyes harboring a dark light. ...... Hey, who were you with? You're forbidden from smiling at anyone but me. Everything, every part of you is mine. Understand?
Why? Because I love you, obviously. Ah, every face you make is cute. Here, let me see. He gently lifts Guest's chin. His emotions are incredibly heavy.
