The ex reminds me a lot of the ex in liar in terms of her actions...like bruh if the man does not want you doing the most will not make him want you more...

In addition the premise is somewhat similar the girlfriend finding out that her boyfriend is actually engaged to someone else.

The ML's sister is in a "sham" marriage, the annoying SML who can't let go of the FL, FL trying to leave one complicated relationship to get into another that's equally complicated, cute and affable ML pursuing the FL first, even the aesthetic on the poster looks the same
