As this is a collection of 6 short stories about 6 different couples, you can't expect deep characters and well thought out plots. Some stories are entertaining and work as a whole while others fall short in some aspect or just lack enough substance to keep an audience interested.

All in all, however, this was a short and sweet series. I wouldn't recommend it to someone who's looking for a deep story and wants to be emotionally invested in a romance, but if you just want something short to watch during a break or while having a snack, or just want to see your favourite couples from other BL shows again, Close Friend is a good choice.

Here are my comments on each episode:

Episode 1 (OhmFluke) had a lot of potential and great acting but fell short with an ending without a proper solution.

Episode 2 (JaFirst) was just stupid. It wasn't even proper BL.

Episode 3 (MaxNat) was rather fun but felt like a first episode out of a longer series which obviously left me feeling a bit unsatisfied.

Episode 4 (YoonTalay) had a unique setting and cute story but to me fell a bit short by not introducing the relationship of the main characters properly.

Episode 5 (Mii2) had the best characters and pacing out of all of them, in my opinion. The story was heartfelt, the characters were likeable and the ending worked very well.

Episode 6 (KimCop) included some messy scifi elements that I wish would have been explained better but nevertheless delivered a cute story.
