This is one off the BL I prefer, mostly because of the great actors and cute story of the main couple and I must say, even if TinCan love story isn't really original, it remains cute anyway.
I usually don't like to re-watch series because I am not surprised anymore but, again, the story main story is so sweet it makes it easy to be tempted. AePete are a wonderful couple and I totally disagree with those saying they can be boring. They take their time to make their relation grow and it really works, they are natural in their interactions and really mature by talking about their problems, they clearly trust each other and it's heart warming.
TumTar storyline is also really important, it shows repercussions off rape and the desir to help the other without being able to do something except to bring support and understanding. Loved it

Now... The main problem: consent. I know I' m not a part of a minority on this point. KengklaTechno story is... Horrible and it entertain rape culture kengkla raped Techno for God's sake! And after that, I had seen in season 2 trailer he makes him feel bad and wants him to "take responsibilities", it makes me puke. This guy is nuts, he is a psycho who is obsessed with his best friend's brother (who is horrible too BTW, seriously who sell his brother's ass for services) to the point that he sabotage his motorbike! And then he abuse him while he is drunk! I will never support this kind of love story.
TinCan relationship, despite the fact it's cute to the end has some problems too, because there is no consent at the beginning and some blackmail from Tin but it is not as bad as a rape of course :3
