I do not care if he hates him or something. I just care that he doesn't assault him etc. That would be a red flag, not this. I like him as a "knows literally nothing" kinda character. Also I don't think he hates him I think he doesn't even know what "liking" means. He is like a child who doesn't know anything about everything so we have to wait and see. In the meantime I think he will do bad things like killing people but I don't expect him to be a bad person towards the teacher. Just because he doesn't even know how to like someone and act. He just goes with the basics. Believe me, he is gonna be good (not now but in the future) and mark my words, we will be okay.

Green or red?

Seme acts sweet, open and even vulnerable around uke (he acts a bit like a jerk on bed but it's fine, it's hot lol), though is obvious he is doing all that because he finds uke interesting and fun and is playing around with uke, it seems there's a bit of honesty in his actions so I can't be sure.
My verdict as of ch 14, is green.

Read raws, and though I don’t know what built up to it, Seme drugs Uke, puts him in cuffs, and rapes him. After, the uke doesn’t seem to be that mad tho? And like..it doesn’t look like it came from bad blood or anything. Idk the raws are kinda hard to understand. If anything: Non-con drugging & Non-con touching
This story is literally a perfect one. Not even one flaw. Art style, character development, love and passion. What more a fujoshi can want?
