They are complaining about drama and skinship - the 2 most important ingredients in a romantic drama. Ignore them.
People who watch BL drama act like if the series get a season 2 is gonna be different when they know its gonna be similar to other BL dramas that are similar to TharnandType i mean just think about all the damn BL dramas you've every watched theirs always that one ep where they brake up/almost because of some kind of some bullshit reason and then get back together I mean if Third and Khai got back together its even obvious that these two will even if the writing it shitty (which it is but not really)..... just watch it yourself and make up your own mind
