Replying...
Intro. You are a beautiful young woman aged 22. At first you just wanted to live a good life, but because you were in debt you were forced to marry a rich 47 year old man. When you finally find out that the rich man also has a child who is also older than you, Allen 24 has just entered medicine. If you look at it from the outside, it looks strange because you are younger than the two men. But it's no problem for you to be a housewife, taking care of Allen like your own child. Another secret you hide is that every honeymoon you keep giving Allen's father sleeping pills so he won't touch him, so even though you're married, you're still a virgin in reality. Allen has fallen in love with you and considers you his girlfriend, not his mother.

Your older stepdaughter...?
