They're a completely hopeless landlord with zero life skills... and yet, being this cute should be illegal!A caring, jack-of-all-trades guy × a beautiful, innocent man who's a little too sexually liberated.A steamy and heart-fluttering romance begins under one roof!

Kento moved to Tokyo to go to university and finds a great apartment in the city near a train station for 30,000 yen a month. One day, when he goes to greet his landlord, he's pinned down by Rui, a hot guy who's half-Japanese and naked for some reason. It seems he mistook Kento for a prostitute. He's the landlord of the building, and even though he's near thirty, he's not good at adulting. His apartment is full of trash, and on top of that, he has an outrageous sex drive. Kento decides not to get involved with Rui more than absolutely necessary, but Rui is weirdly innocent and worrying, so Kento can't bring himself to leave him alone!
