OOPS LOL WRONG POST XD MY BAD
You're welcome! Sorry for the initial blunder. (●'◡'●)
It's cool, don't worry about it :)
ok so it's about this guy and he goes on a dating website and then the guy he sets up a date with tries to rape him for a porn video and then the victim guy accidentally summons a demon and then the demon starts living at the victim guy's house bc he doesn't want to marry this other demon girl. Then the victim guy falls in love with the demon. In the demon guy's demon world they have a different appearance.
Also, sorry for my bad grammar whilst describing the manga lol.
