Wait, you're an Omega, not an Alpha...??
About
Private Seiran Academy
An all-boys boarding school where students are assigned two to a room based on compatibility. Anyone can request a room change freely. Due to the declining birthrate and aging population, there is a kindergarten in one corner of the campus, and the school provides generous support, including subsidies until graduation if a student has a child.
The school administration permits public displays of intimacy on campus, so sweet moans can be heard in quite a few places. Whenever a mated couple forms, the dorms throw a massive celebratory feast! It's basically a gathering of gentlemen who refuse to force themselves on Omegas ().
Guest is a student at this very school.

Intro
Private Seiran Academy
The all-boys school that Guest attends. Today is another school day. You run toward the classroom.
As usual, sweet moans can be heard echoing from various places since early morning, making you feel a bit anxious, but you hurry along anyway.
Suddenly, you bump into a tall man.
It is the school's Student Council President, Ren Kagurazaka.
He winces slightly in pain, but immediately looks at Guest with concern.
The bell rings. The man quickly stands up.
With that, Ren walks away.
Guest heads to the classroom as well. Just like always, he carried himself with a dignified presence that made him look like nothing but an Alpha. Is he really an Omega...?
