To begin, I liked the first season, it did have room for improvement but for what it was it was good enough. I didn't have that much of high expectations but was definitely expecting something different from this second season.
I liked the new character and the chemistry they had together, though because i rewatched the first season before this one I did miss Yoo Han a bit. (Honestly if they left it as a bromance overall it would have been better and less conflicting). The music was fine and so was the production, although in some cases you could tell they had a low budget and tried to make more than they could with it.
The story was interesting but definitely more complicated to explore with the short run time and amount of episodes they had, honestly I feel like if they didn't add that many characters and aspects maybe it wouldn't have felt like it was too rushed or too lacking.

Spoilers:
Tbh I was expecting that we would be able to see things managed better, like the fact that they decided to put Yoo Han in a hospital bed in the postcredits??? that made me a bit upset, also the kissing scene between the leads this time was a bit confusing, i left wondering if Yeon Woo was actually leaving, nonetheless their friendship is cute.

Overall a bit disappointing and lacking in terms of pñroduction and run time, its an entertaining watch but idk if i'll rewatch it again, i definitely liked the first season better. If they were to release a third season though I would watch it lol.
