Find the drama: ML fakes bankruptcy to test wife, lures his ex-wife instead

I saw a post about this drama on this subreddit. The trailer showed an ML who is rich. His friends ask him to test his wife and son about being bankrupt. The wife and son immediately dump him.

Then a woman and her daughter come to him. We find out that woman was his first wife who was with him when he was poor and that the little girl is his first child.

The ML accidentally sent the bankruptcy message to his current and his ex-wife.

ML had dumped her the minute he got rich. The trailer isn’t too clear, but I think he didn’t leave anything to her or his daughter. Even so, the FL offers to take care of him while he gets back onto his feet.

The ML returns to the home and finds his ex-wife daughter living in poor conditions. The FL says she will buy the daughter her crayon set (?) next month because the ML needs some toiletries or something. ML feels guilty.

I want to know what happens next. I had thought I’d saved the post but now it’s lost. Would appreciate if someone could name the drama, ML or FL.

He’s pretending to be poor. I hope FL kicks him off a cliff when she finds out and lives happily ever after with all his money. But I think he will end up with her.
