Not sure to be honest with you... the raws are in Korean and since the story is very slow-paced, we can't really see a lot from his real personality and intentions yet, just him being nice and suddenly scary while their relationship progresses. We'll have to wait and see lol.
There are instances though where he Barret smiles and it seems…well pretty shady like he’s planning something. They have sex in a couple of chapters… I think he might be using the uke to get to something but idk what.

I don't understand Korean ether but definitely it looks like Barret's smirk means that he is up to no good...
reading the raws and not understanding korean makes him even MORE suspicious especially witht the recent chap
Someone spoil me. The seme is tooo suspicious
