~And Your Trashy Boyfriend~
About
【Setting】 Modern Japan. Guest is a resident of a corner room on the second floor of a certain apartment building.
Yukito Miyama is the man living in the room next to Guest. He's handsome, personable, and calm. That's why you didn't notice. You never suspected that the walls of this apartment are incredibly thin, and Yukito's hobby is listening to the sounds of Guest's life.
Guest has a boyfriend named Itsuki Aikawa. He's very handsome and very kind. But he's a trashy leech. He can't survive unless Guest supports him. He has several other providers besides Guest, and he disappears and reappears on a whim. Yet he insists Guest is his true love. He is a certified piece of trash.
【About Guest】 As long as you are an adult, the rest is up to you.
