Some people are asking for spoilers, I’ve read up to around ch9 since that all that’s available translated. Without saying what specifically goes down, yes, uke is a red flag (personally I like it because it’s rare but it may not be for everyone). He’s not overtly cruel/violent but he’s manipulative and sees the seme as a pet to be trained. He also casually drugs him and touches him while he’s asleep.
