This show does not follow the traditional BL path. You have to be willing to watch with an open mind and accept the fact that things will not go as you expect. If you are willing to do that, you are in for an experience!

This show is aimed at a more mature audience. It doesn't only feature mature adult characters on paper - these characters actually live mature adult lives. They struggle with real issues, doubts, insecurities, and hang-ups. The characters are allowed to make mistakes and experience the consequences. It shows what real-life growth looks like. This show doesn't waste our time with fantasy and magic solutions, it does however, use the fantasy element of the soulmate connection to show how damaging it can be to relationships when you expect "magic" solutions.
This show is about making relationships work in the real world. This show is about communication. I think that what I love most about this show is that it uses a fantasy element to tell a BL story (a fantasy in itself) and ends up being the most realistic portrayal of actual relationships, of any kind for that matter. You get parents/children, brothers, romantic relationships, friendships, divorced couple. All are represented truthfully and thoughtfully.

I saw some reviews saying that the characters behave off-character and there are no explanations for their behavior. I think that this is a very surface level read of these characters. I would encourage you to re-watch the series and see how EVERY ACTION is justified and based in each character's actions and thought process since ep 1. Everything these characters do is justified and we are blessed with a show that really sees its audience as intelligent viewers. It doesn't insult us with useless expositions or characters that scream the subtext. It shows and tells its story in an intelligent, thought provoking way that is so satisfying to watch.

So, if any of this sounds good to you, you WILL enjoy this show. Just remember to come clean of the usual BL expectations and really watch the show.
