Short and simplistic. I saw the 8 rating and thought I would give it a go but it didn't work for me.

The good
On the face of it, this a story about a young man overcoming his insecurities and finding love. The setting of a university film class is also interesting. I'm sure the anxieties of being handsome and popular is something most people can relate to. It was refreshing to see the role reversal of a ML lead in this situation and is reflective of modern life.
Kang Eun Bin does a good job of showing the facade put on by Si Won and the anxious person beneath it all.
As other reviewers have said, it's positive to see an LGBT romance that is not immediately shunned by the other characters. However, this series seems to skirt around the issue altogether, with all the romantic scenes separated from the rest of the cast. I won't complain too much though because there is a decent amount of intimacy between the two leads.

The bad
Far too short to have a developed plot or characters. Unfortunately, this is often the restraint of this genre but 12 minute episodes really did not work for me. I could understand and appreciate Si Won's character but there wasn't much time for anyone else. This wasn't helped by the fact that there was limited dialogue.
Da Un felt very wooden as a character. We get glimpse at his backstory but it is never fully explained. He spends most of the latter episodes looking solemn and not saying much. I found the apology scene in the final episode particularly unconvincing.
All in all, it lacked the subtlety and chemistry of leading genre dramas such as To My Star. Perhaps if the episodes were 20 min they might have been able to do more.
