I enjoyed this show.
I'll start with the cons and there's only really 2
1- I feel like we were teased with the GL or not GL. I'd like to see them commit to that in season 2.
2- the artsy nature of it sometimes made the story and bit loose and hard to follow. though I understand this may just be due to my taste and watching it at 3am.

Otherwise there's so many pros. the acting was SUPERB especially in the last episode. I loved that they didn't shy away from romantic intimacy. it wasn't angsty or pushy romance it was easy, soft and beautiful. the filmography was splendid and I think overall it was just a very beautiful and comfortable watch.

I'd definitely say watch it. it wasn't my usual style so I am not sure if I'd watch it again but I definitely enjoyed it and if you like Korean BL this one is definitely one of the best I've seen.
