Haruhiko is a jealous middle-aged man living in an apartment. One day, a beautiful woman named Sayaka moved to the room next to Haruhiko! When I hear a little talk of greetings, she is said to be married. but if you look at that chest, it's super cool... What a nobra! Haruhiko can't hide his excitement from unrealistic events. In his head, Nobra's whimsical figure ran around and he couldn't leave.
