The Emperess
I know she won’t be able to divorce him... I’m looking for a book where the fl says she’ll divorce and actually does.
It's technically not a divorce, but the fl died after being married to the ml and reincarnated as a young girl again and because ml treated her coldly, she doesn't want to be together with him. Regardeless, ml suddenly acts different then before and want her as his girlfriend, then marry her etc. The name of the novel is "Run, girl (if you can)". It is an original on webnovel.
