Although I rate this drama with "only" 7 stars, it isn't bad at all. 7 is for me a light, fun watch, where I don't have much to criticize, but where I also wasn't that much enganged. :D

What I liked:

First of all, I was suuuper excited for Ahn Se Min, but found his perfomance the weakest.. Therefore Kim Sung Hyun surprised me. I really liked his acting/his character and he made me smile here and there. Overall, all the characters were pretty much likeable and entertaining.

The ending OST is a bop! Love it.

I actually liked the haircuts and the fluffy pastel sweaters. :D Jung Ki Sub was such a fluffball and endlessly adorable. Some scenes were really cute, funny or just nice to watch.

Room for improvement:

I agree, the writing was weak. The story felt choppy here and there and it was rather shallow. Some circumstances could have been used in a more emotional engaging way. I just didn't care too much about the characters, buuuut I really enjoyed one scene in episode 7 and a lot of episode 8. So..in the end, I was actually happy about the outcome. :D

It's just a classic, light korean BL. I don't think you miss a lot if you skip it, but it's also not a waste of time watching it. It's just nothing that hooked me emotionally or made me really feel connected to the characters. But I love korean BLs in general, so I don't miss out on them. :D

Additional thoughts:

I think a lot of people lack psychological understanding to get the characters at some point - based on what I read in the comments and where I absolutely can't agree with. I started the show, read some comments and were pretty bummed, because I expected the worst. :'D But yeah, it's not bad and for me the, the actions were all logically and understandable. I won't elaborate any further, because I want to keep my review spoilerfree. :)
