It started off really well, but towards the end, it felt rushed. I think it's a common problem with k BL dramas; they're often quite rushed. Either they need to make the episodes longer, or they need to increase the number of episodes, in my opinion.

I'm personally not a big fan of love triangles, but I'm not against them either if they're done right. However, I didn't like it here; it just didn't feel right.
And one thing that makes me wonder is why they didn't feel the need to talk after their first kiss. I mean, they kissed each other when it actually wasn't the best time to do something like that, and the next day it felt like nothing happened. Isn't it a bit unrealistic? And personally I'm not a big fan of it's writing.

Overall, it's sweet, but I still feel like it's rushed and could've been better.
