it gives me the same vibes, past lovers that reunite, a story about love and fate, I don't wan to give away more and spoil the movie

Both contain abusive manipulative male leads, I think both are entertaining, I just love to hate the male leads and drama

Both raw indie like romance movies, only that in Theater a Love Story" is the male lead that tries to chase his dreams

They both start with an explosion and have a little comedy, the story also include gangs and violence , both have good acting.

Is also a "slice-of-life" like drama that even if i"it doesn't involve social media, it also focuses on married couples, affairs and divorce

The movie version has a different end. The series are based on the movie, only that in the series they meet 8 years later.
