I don't hate her but I don't want her to mess things up.

We need some drama to justify the continuation of the story. Im glad she showed up. They probably broke up because Taesung liked Haebom since back then anyway.

I think the same it's always easy to understand what happened before, but of course I want the details and stuff

I know. I was glad to see her come becaus ethat means we have more chapters ahead.
