Sing My Crush is a sweet, breezy little drama that manages to keep a good balance of fluff with a little bit of angst and drama to keep it from being cloying. It's easily bingeable and can be completed in an afternoon and is a great de-stressor after a long day at work. I speak from experience. The characters are endearing, the plot simple, and the music divine.

The story is simple and it's simplicity is an asset considering the limited number of episodes. There are no deep dives into the characters' backgrounds, no real flashbacks, just a steady progression as the characters grow and it works. The story is overall cohesive, there are a few loose threads, the issue with Sangin doesn't feel fully resolved, for example, but nothing huge to complain about. The pacing is steady and overall well done despite a few laggy moments, but they're not enough to hold the story back too much.

The characters aren't overly complicated; on the surface, they're fairly transparent.
-Han Ba Ram is a sweetheart who, after being burned by love, is a bit hesitant to confess again. Being gay also complicates the matter and elevates his fear, so he keeps it a secret and continues living with the man he loves until his first love re-enters his life and complicates things. There's an element of frustration with him, the feeling that wouldn't it be better to just confess and get rid of the proverbial sword hanging over his head. But, having been in his shoes, I can also understand how incredibly difficult it is to confess, especially when you're afraid of ruining the friendship that you have. I was impressed with the character growth seen in such a short period of time. You can really see his confidence grow both in his music and as a person.
-Im Han Tae has to be one of the most dense characters I've seen. I truly thought he was already in love with Ba Ram up until Ba Ram confessed and he was totally clueless. His actions and behaviour afterward left me alternately laughing in exasperation and wanting to bash my head against the wall. It's a good thing he's cute. Nevertheless, I appreciated his loyalty and steadfastness when it came to Ba Ram and even when he wasn't 100% certain of his feelings, he still took care of and protected him.
-Sangin annoyed me from the get go and just got worse from there. He was far too handsy for any kind of reputable teacher and the way he baited Ba Ram into trying to kiss him to prove his love was disconcerting. Coming back after the fact and trying to steal Ba Ram's song was the cherry on top. I found it disappointing that he never once took responsibility for his actions, but continued to blame Ba Ram till the end. As a side note, he seemed too old be debuting, not that I'm any kind of expert on that and frankly I think expanding the age range would be great, but realistically, I didn't buy it.
-While they didn't play huge roles within the story, I liked Young Mi and Jeong Pal. They were cute as a couple, but I also liked their friendship and dynamic with Ba Ram and Han Tae.

The acting was good all around. Do Yoon and Hyun Woo had good chemistry. Even their first kiss, which I would normally consider a dead fish lip press, actually worked for them. It was hesitant and sweet and felt realistic for a first tentative kiss. They just seemed very comfortable around each other and I liked them together. I felt both actors did their character's justice.

I loved the music. Both "Letter of Apology" and "Second Wind" are beautiful songs. "Letter of Apology" was utilized throughout the run but it was done in such a way that I didn't get tired of it or feel that it was overplayed. The rest of the music was pretty generic but those two definitely stood out.

This is not a deep drama, it's too short to delve into any kind of real issues, and again they were smart to keep it simple. But simple doesn't mean without it's merits and it does touch on elements like having confidence in yourself, growing as a person, and pursuing what you love. I found it to be an enjoyable diversion for an afternoon and one that I would recommend and will likely come back to in the future.
