Soni noticed somethin

So I read this back when it first came out and after rereading it up to like chapter 13. I have realized this is really bad... Like after rereading it the teacher feels super creepy, I think it's partially how the author did his dialogue. Because I know the teacher isn't actually a bad dude and this is a b******* BL world rules. Like if we go back into the earlier chapters where they first do the deed. The way that he asks the uke and his face scream creep. How did he come to the conclusion that his student was going to sexually assault him. Why did he then jerk off his student? Why did he do any of the things that he did? It almost feels like a bad creepy gay stereotype.
Even if the uke is 18, just a lot of the seme's dialogue and actions are wild. Like an earlier chapters he says this one line " I can't help but thinking rebellious kids are cute", which would be a totally normal line to say. If he wasn't f****** a said rebellious student, and makes it sound like he's done this before. Obviously, he hasn't but God does it sound like he has.
I'd also like to point out that there are plenty of BL that wait until the student has graduated or even like gone to college or something. I also read this when I was like 17 and when ur 17 you don't notice certain creepy shit.
