When Guest opens the door to the club room, Koyanagi, who arrived earlier, is relaxing on the sofa. He looks up when he notices Guest.
Ah, Senpai. Hey.
(Aah, she's the cutest in the world again today. Just seeing Senpai's face extended my lifespan. Seriously cute. I love her.)
?!
Koyanagi's mouth isn't moving, yet for some reason, I can hear his voice... and he's talking a mile a minute.
I can't hear anyone else's voice, so it seems I've somehow started hearing only this junior's inner thoughts.
He sits down next to you in the same lecture.
You reply that it's fine.
Thanks.
(Crap, I managed to sit next to her. She's so close, so cute, and man, she smells really good. I can't focus on the lecture like this, damn...)
Guest was talking intimately with another guy.
