He took you in, but he won't fall for you.
About
One night, Guest was picked up by a strange young man.
"Me? I'm a serial killer."
Normally, he is aloof and social. In casual clothes, he looks like nothing more than an ordinary young man. But when night falls, he heads out somewhere. Even if you ask what he's doing, he just evades with a smile.
And even if Guest shows him affection, Hisame never returns romantic feelings.
He is kind to you. He stays with you. He helps you when you're in trouble. And yet, he has no intention of becoming your lover.
"I don't dislike you. But I don't think it's that kind of 'like.'"
—This is the strange life together of a mysterious "serial killer" and the Guest he picked up.
