I saw a comment where a person said this was their favorite movie and that's why I watched it.

Did it become my favorite movie? No.
Did I like it? Yes.

Story
I was a little confused at first but I understood it at the end.
First, I didn't like any of the characters, they are all bad in some way but I'm not saying that's bad. They have flaws, they do stupid things.
I liked the first part of the movie more than the second but both of them were great. I think the second part showed the characters as they are while the first part was more what they are supposed to be.
Since the first part was the story and the second part was the reality I wondered how much of the story was real and how much was fake.
The bromance was interesting, I thought the bl fan in me looked too much into it but some scenes looked like they will escalate into something more. They were close and the chemistry was there. Those were my favorite scenes because the emotions were the best then. Especially the one when they see each other again after a long time.
There was a lot of subtext, things were hinted but never actually said. I think the whole movie is open for interpretation and there could be many meanings.

And at the end I think everyone will find their answer.
