Fl doesn’t/no longer loves ml, he regrets (Straight, Manga)

Ml is a terrible fiancé who doesn’t make any effort to make her happy and never initiates contact. Misunderstandings ensue. He’s very clumsy in trying to fix it and fl has decided not to expect anything from him.

Honestly wish he would just be forced to give up and let her live her dream. She wants to study! And work! Let her go, dude!!

Ml marries fl to appease family because he has a lover they don’t like. Fl doesn’t want love, only to live how she wants. They live separately, mostly ignoring each other. Servants love fl. Ml starts noticing how lovely fl is. He starts falling in love.

Remilia, the villainess/fl, has her body possessed by Emi. She watches Emi live her life, avoiding a bad end for her because she loved Remilia and wished for her happiness.
