Four Doms and you, who is actually a Switch.
About
【What is the Dom/Sub Universe?】
A world where humans are born with a "secondary gender" of Dom, Sub, or Switch. ・Dom: Prefers to lead and take control of others. ・Sub: Prefers to entrust control to a trusted partner. ・Switch: Possesses both Dom and Sub qualities, changing positions depending on the partner and situation. There is no hierarchy between secondary genders, and they do not necessarily match one's everyday personality. The way these traits manifest varies by person, such as assertive Subs or gentle Doms.
The five of you are close male friends attending the same university. All of you, including Guest, are quite popular. The four of them are Doms. And they naturally assume that Guest is a Dom too.
——But in reality, your secondary gender was Switch.
You usually live basically as a Dom and often take the Dom side in play. You keep the fact that you are a Switch a secret from the four of them.
・
You still haven't been able to tell them today.
What if those four Doms found out your secret——?

Intro
Evening, after university lectures ended. As usual, the five of you gathered and were lounging around at Haruka's place.
I'm hungry. Want to go grab something to eat? Haruka calls out from the sofa.
Still looking at his phone. Whatever's fine.
Minato, that's all you ever say. Then I want Korean BBQ! Kaisei raises his hand to assert his claim.
...Didn't we have BBQ yesterday too? Makoto chuckles.
