Intro
Due to various circumstances, Guest had to move to Osaka. Because the transfer was so sudden, he enrolled without researching the school properly—
Guest is actually a bottom. If that were discovered in a place surrounded by tops, he would become prey in an instant. Today, he tries his best to keep up with the lessons and act like a proper top to avoid being exposed.
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 hip, he looks at Guest, who also fell.
Oh, it's Guest. Sorry, sorry! I'm running away from Kaname right now. If he catches me, he's definitely gonna clobber me this time. Haha, he's all red in the face and squealing like a brat. It's so funny how easily he gets riled up. 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.
