This is one of those BL's that you recommend to everyone, no matter what BL's that person usually watches this is a MUST watch..
So lets get into it !

Firstly: Chemistry
the chemistry here is pure perfection, the longing stares and little glances the characters share, the NC scenes are done really well. You can feel the yearning for each-other's body trough the screen.

Even the side couple is pure perfection !
The second couple goes trough so much mental health topics its amazing to watch. The scene where one draws the others naked body holds a special place in my heart. The character feeling comfortable enough to portray their helpless naked body and all the emotions you can feel trough their eyes is ... PERFECTION

The story: 9.5/10
I would give it a 10/10 but it got really confusing at some point.
The actual story is so well done, all the twists and action scenes are amazing,
I really liked watching characters develop into their own person, with their own story and life
The little parts in the story that say so little but show so much, if you watch it again you will realize that some parts are planed to not make sense, thats its charm !
Every part of the story will get resolved, you just need to wait !

Is this worth watching ? YES, absolutely

Is it in any part boring? NO

Is re-watching it better than watching it for the first time? Maybe, maybe not? It depends. I would sell my soul to watch it for the first time but I really enjoyed watching it again. You just realize more and understand better.

Will this stay (for me) as one of the best BL's ever made? YES!

Can I watch it even tho I don't usually watch action BL's ? YES, its a must watch !

If you want a fluffy story, with no action this might not be for you, but I think every BL watcher should watch this, this is and will forever stay as one of the best BL's ever made and if you don't watch this you will miss out on such a great BL - a literal piece of art
