First of all: if you watched the first episode and you're considering dropping the series altogether because of how the main characters seem to be like, please consider watching a couple more episodes. At the beginning I was actually considering dropping this series because of how Bai Lang seemed too spoiled and childish, while Xun An seemed too grumpy and cold - a combination I saw too many times in romantic series, I'm afraid. The story and the introspection of the characters do a marvelous job at portraying both of them much better in the following episodes.

This series was pretty cute, and I mostly appreciated the original take on both the plot and the character introspection. The main characters have both their own emotional problems and ghosts of the past, but at the same time this isn't one of the usual "who needs therapy when you have a boyfriend?" kind of situation. The slow but steady development of the relationship between Bai Lang and Xun An was beautiful and I enjoyed it very much. Also, although this is more of a personal preference, I really appreciated how the problems between the two weren't the usual misunderstandings and "let's just disappear and have a very long time skip" sort of problems that BLs use way too often, but rather problems that might occur to a real couple.

Unfortunately I can't say the same for the secondary characters. I feel like the writers tried to include too many stories in the same series, which only resulted in frustrating, barely-there side plotlines. There was a lot more to show and tell about Qing Tian and Alex and their story just left me wanting more; as for Da/Xiao A and the hockey player, I'm still wondering who thought it was necessary to include their romance in the first place.
I also didn't really like how Qi Ran's character was introduced in the story. I feel like the production team worked hard to show us his character and his past with Xun An at the best of their possibilities, but I was completely unable to enjoy it - if anything, I felt bored.

In conclusion, I'd say that it was a very cute watch, and the actors played their roles very well. Although it's far from being one of my favorite BL series, I'd recommend watching it once if you're looking for something romantic and with the right amount of drama.
