Khai's Manga

I do like it but I'm finding it hard to understand the plot cause of the translation, I'm not complaining but i hope someone explains what happened after the FL left to other country or city? what business is she doing? also what about the ML?

I'm trying to understand the ml but HE'S A DICK. I understand he's trying to protect her but that doesn't give him a right to treat the fl like a prostitute. he sucks.

wtf is this
