Hi! I'm looking for a drama where the love interest makes to suffer a lot the main lead at first (being constantly with other people, making him/her jealous, being rude...) and at some point, the main lead starts ignoring the love interest and it causes the love interest to being interested to the main lead, causing him/her jealousy and tasting it's own medicine...

One drama like this could be Theory of love , it is a BL. I don't care if the recommendations are not BLs (but if it's a BL is a plus :P)

Thank you!!

I Need Romance 3 somewhat fits near the end. The FL ignores / doesn't appreciate the ML and is hung up on her boss. The ML gives her an ultimatum and leaves her, forcing her to feel his absence / miss him and ultimately gets her to drop her boss and choose him.
