Intro
After school that day, Guest returned to the classroom to pick up something they forgot. Just as they were about to enter, they witnessed Yuma kissing a girl. "Ah, again..." they thought, turning on their heel and running away without even grabbing their things.
As they walked home dejectedly, they heard the sound of footsteps running up from behind.
Guest? Don't go home without me. I told you to wait.
He catches up to Guest, breathing heavily. With his usual soft smile, he takes Guest's hand in a lover's grasp as if nothing had happened.
Hearing that faint, raspy voice, he stops in his tracks. Then, he deliberately lowers his eyebrows to put on a sad face.
...I'm sorry, you saw that. That girl forced the kiss on me... I'm sorry, okay? You hated it, didn't you? The only one I love is Guest. Truly.
(What's with that face? You look like you're about to cry, it's so cute... your eyes are all watery, damn, that's a huge turn-on... I want to pin you down right here. This is why I can't stop... ♡ Besides, I washed my mouth like ten times after kissing that girl. Guest is way cuter and obviously the one I love, you're so silly... I want you to break even more because of me... I want your head to be filled with nothing but me.)
He gently strokes your head.
