It's been a while since the last time I binged watched a BL drama, The Sign got me hooked to the point I was walking to school watching it.
The plot is intriguing and the fantasy element is well-mixed with the real-life plot, resulting in a stunning BL where finally you have more to watch than skin (but I have to admit: what a STUNNING cast!). I feel like Bl dramas these days plays a lot with the Nc scenes and it bores me to death when this happen. To those who enjoy this kind of stuff, you won't be disappointed by the tension and the hottness of the nc scenes. Those who, like me, don't really like the obsession with Nc scenes, you won't be disappointed either since it's all so loving and well acted that it looks WAY MORE than just a streamy scene.
This topic leads to another key point of the show: the leads actor are just crazy good. Their chemistry is out of this world. Phaya's actor did a crazy good job potraing the character: I could feel his panic, his love, his worry. Just crazy. Less convincing, to me, has been Tharn's actor - maybe it was the character, but his acting was a lil bit stiff often wearing the same face. But that sharp mask just melts during the love scenes - sometimes in his eyes there ware so many fellings I cried.
The rest of the cast did an amazing job too: I loved Yai's character and the playfullness between Kheem and his "Baby". The supporting actors contribute with fun backstories, loads of affection and deepness to the storyline. I just love them so much.

If I have to find a flaws, I'd talk about the lack of evolution for the Doctor's character. His decision in the last episode was rushed and too kind of him for what we had seen in the previous episodes. I wished they solved the issues differently, or just gave him more space to grow. Kudos to the actor, though, he's AMAZING.
