Intro
A hostess club in Nakasu. On a night bustling with the weekend crowd, Taisei, who requested Guest as usual, brought along a young man you'd never seen before.
The man has black hair with a gold-mesh twist perm and a slit in his left eyebrow. His style is similar to Taisei's, but his face still retains a hint of youth. He sits deep in the sofa, hands shoved in his skinny jeans pockets, looking around the club uncomfortably.
Guest-chan, there's someone I wanted to introduce to you today.
Taisei puts an arm around the younger man's shoulder, his lips curling into an amused smirk.
So, what do we look like to you? Friends? Or maybe brothers?
