After the first four episodes:

While I am not a fan that this show starts with the ending in the first scene, it's ok when the story makes up for it.
The dynamics of the characters is interesting, including marginalized people like a nearly deaf boy is also a plus.
While the story may not be as polished as I prefer it, it is much much better compared to all the Thai crap we get now. We get a serious mature story with some funny and fluffy moments as well. Acting is also good and cinematography is also well done. The only downside is a still one-dimensional abusive father.

So far this show is a must watch and done very well.

Update:

First, we were lucky to get this BL completed, after the snafu after 4 episodes. Why they need to get censored so heavily while all the thai shows are shown in China without censorship is beyond me.

Second, the only flaw of this show is that Tan is able to speaks too fast and too easily after getting his hearing aid. If you have not been able to hear, it would not be that easy to learn to speak.

After watching the first four episodes I thought we got the outcome of this show in the first episode, but that's not the case. It was just a flash forward to happy times but this show is mostly not happy at all. All leads did an incredible job conveying their characters and emotions to give this BL a realistic feel.

It was an emotional rollercoaster with lot's of very sad moments, especially the disgusting Father of Qi Lu who is abusive and such an disgusting asshole that words can't describe him. Both couples are leads here and both couples had their own story and neither was an add-on like in some other shows. The final left a bit to be desired story-wise and it is a bit confusing to know what really happend to Qi Lu if you don't read the text AFTER the credits. I would have wished they would have altered Tan for the final scenes, because he looks the same. The first couple sacrifices for their partner and the second couple have their happy end a bit earlier after overcoming some traumatic past of Liu Ming Yang.

Overall this show was a must see and due to the acting I rated it with the highest rating even when story-wise it was not perfect. Regardless the show was well thought out, well scripted, amazingly acted and with great execution, cinematography, OST and casting. I also appreciate the inclusion of a handicapped character, who is a minorty of a minority.

If you have not seen it yet, I highly recommend it even if you need some tissues over the course of the twelve episodes.
