What happened after transferring schools

I can't really introduce the work!! Hahahaha Hmm... So the female protagonist transfers schools, meets Taehyung, and remembers her past, and Taehyung is in that past! And then they get married and have a child, haha. She's a bit of a bully, hahaha. And I'm a pervert, so there are a lot of dirty stories, haha.
