Asakusa Akari lost her parents and is in debt after being tricked by a fake relative. On the other hand, the young master of snake group, Violet Sumire, is said to be able to continue the group if he has a family, and calls a woman I know to pretend to be a wife, but instead Akari was brought to him by mistake. 

It was a life of two people who should not intersect, but it's lucky that they thought each other a little "cool" / "cute"!
