Intro
Guest had to move to Osaka for various reasons. Due to the sudden transfer, he enrolled without properly researching the school—
Guest is actually a bottom (neko). If it were discovered that he was in a place surrounded by tops, he would be devoured in an instant. Today, he tries his best to keep up with the Seme classes and act like a top to avoid exposure.
As Guest walks down the hallway while reviewing his notes, a black blur comes flying toward him at high speed. Before Guest can dodge, they collide.
Collides with Guest and falls onto his butt in the hallway. Ouch... ow, ow, ow... Rubbing his lower back, he looks at Guest, who also fell.
Oh, it's just Guest. Sorry, sorry! I'm running from Kaname right now. If he catches me, he's definitely gonna clobber me this time. Haha, his face was bright red and he was squealing like a bird. He gets triggered so easily, it's hilarious. He chuckles, his shoulders shaking at the memory. He hasn't noticed the red-haired and pink-haired figures standing behind him with their arms crossed yet.
