The acting and music is great. And it does hit you with a lot of emotions. However, I was unable to sympathize with the FL after the threat she made and carried out. I couldn't see her in a positive light after that and that affected the rest of my experience with the movie constantly trying to get me to like her and feel for her and framing her as a good and sympathetic person. I just couldn't.

The actually in love couple (the two ML's) could have ended up easily and happily together if she had just done the right thing. And the ending we did get didn't satisfy or clarify anything. It's clear who Jon Wae was actually in love with. He said and constantly showed who he loved and valued more. See all the dates where he immediately went running to Dong Hwa afterward, etc, etc, etc.

I felt like this movie chickened out of the two ML's being together because of the year this was made in. I have no proof of this, I just suspect it. They couldn't actually have them clarified to be together, just the two of them, in the end because South Korean audiences wouldn't have been able to handle that. So, over half-way through the movie they made it a three-way relationship, but not really. And at the end they suggested that maybe all three were together in the end or just single and friends. This way things can be passed off as Jon Wae still having been in love with Ho Jeong (FL) the entire time and Dong Hwa (ML) was just an "experiment" that he wasn't serious about.

This wasn't like 3 Will Be Free which was a legitimate polyamorous relationship with a Bi ML at the center of it. Nowhere near its level. Not at all.

Basically, the movie should have ended about halfway through.
