I watched this after seeing some clips in social media that peaked interest. It didn't quite live up to my expectations though.

It is OK, but quite unrealistic/extreme actions.
Some of the things that pulls it down for me:
How FL is quite immature, none of them communicate well leading to repeated conflicts, and if his coworker really liked him, why would she go to such extremes as to ruin his dream and life?
And how quickly did FL move in to a new apartement? It was like she went straight from deciding to break up to eating dinner in a new apartement. I even skipped back to see if I had missed a text that said "1 week later" or something.

I found ML to act quite well, whereas I am more unsure about FL - might be because of the character.
