The design of characters is good but their personalities suck, I like to read about the kind of decisions that a person would make in a weird situation like always happens in this kind of story I just wish the actions they took were more reasonable who would start licking someone else fingers out of the blue?

I don't know what the sensei was thinking he thinks that having sex with his students is wrong but masturbating next to each other in the same bed is ok?

They were under the effect of the incense drug. Remember the girls cant even keep their sanity when they are exposed to it I imagine it sort of works like a high dose of ecstasy. At that point he was probably doing all he possibly could to keep control and as soon as he figured out what was going on he stopped it. I'd say under the circumstances he acted commendably.
I really like the story it wasn't too sweet like a lot of mangas yaoi or too dark, I liked that the omega kept firm in his decision of not having sex... for a while. Can anyone recommend me more manhuas/mangas were the uke wants revenge or make the life difficult for the seme maybe the seme cheated on him or the uke himself cheated (and lots of drama like in this manhua )
