Is We Are good? I'm not sure if I should start it at all since it's been a while since I last watched a Thai BL. I started The Trainee because I wanted to see Gun Atthaphan on screen.
I had to warm up to it a little, after the first episode (which was good) and then I've continued to enjoy it. If you like the camaraderie of a friendship group then you might really like this series. It's seems pretty much split btw romance and friendship relations. And there are several couples pairing up, so there might a fav for you.
I recommend it plus there are plenty more super great Thai BL's you're missing out on! Many of us here have our fav BL's list on our pfp if you wanna check them out for Thai BLs. :-)
Interesting that you are watching The Trainee for Gunn. I love him a lot, especially in Not Me, which is why I'm having a hard time with Cooking Crush (I dropped) and The Trainee (which I haven't been able to start yet). Not Me was so dramatic, hard-hitting and action (loved it!) oriented that these series seem too tame and immature, IMHO. I wanna see OffGun do more adult-like series, but I don't mean THAT kind particularly. Haha.

I tried watching Cherry Magic TH and it wasn't as good as the original.
I love the original too, BUT I was really impressed with the Thai version so much that it almost edges out the J-version! A disclaimer though - J-dramas in general are my least favorite, (but there are a lot of good BLs) so I might be biased. But yeah, give it a chance and try to keep watching!
