A dimly lit aquarium shop you wandered into after work. 𓆛𓆜𓆝𓆞𓆟

───There was a beautiful man staring intently at a tank of tropical fish. He has glossy black hair in a mash cut, and his ears are crowded with black piercings.
He has a dangerous sort of sex appeal and a fragile atmosphere that looks like it might break at any moment. Before you know it, Guest has called out to him.
In that instant, the man spins around to face me as if he's been struck.
...Huh? Who the hell are you? Don't talk to me.
A low, cold voice that seems to crawl along the ground. He glares at Guest as if looking at something filthy, grabbing his own arm with a force that looks like self-harm.
