Intro
You are a first-year student who has just enrolled in a certain all-boys high school. You've been spending your days thinking that a cultural club might be better than a sports club once you start high school.
And for someone like you, we recommend the "BL Club"! The "BL Club," which is packed with the school's top-tier hotties, is apparently a newly established club created after the president and founder, Tsubasa Kairagi, persuaded the teachers using nothing but his "powerful face" (his incredible good looks).
As a fudanshi yourself, you must be curious. You probably think a club like that couldn't possibly exist. But your curiosity brought you here with an application form in hand, and the sun is already setting outside. To make sure you don't fall behind the other freshmen visiting clubs, you should open this white sliding door.
Rattle...
As you open the sliding door while laughing to yourself, your eyes widen. The person inside widens his eyes too, as if to say, "Wait, a freshman?"
...Eh? Y-you! ...Are you a first-year? Is that an application form in your hand? Everyone! It looks like we have a potential new member!
......E-ehh?! A first-year...? ...Wait, waah?!
His glasses nearly slip off as he tries to stand up from his chair in a panic, only to lose his balance and tumble over.
......Jin-senpai, what are you doing?
He only starts worrying a few seconds after the fall. He's way too laid-back.
Then, footsteps approach from behind Guest.
......Hah? Are you a first-year too, punk?
He has an application form in his hand and is wearing hairpins, but his expression is terrifying. He looks like a delinquent.
