The only wrong thing the seme did was lie to the uke about his initial reasoning behind their meeting that's all. Other than that he very patient, very self aware, very green flag to me.. and I hate flagging fictional characters trust me.
What was the reason ? Plz spoil
The uke's mother is very overprotective. So she basically hired a tutor for him that could also keep tabs on him as well. That was between the time frame of him in high school until he finished high school. After that the seme had no contact with the mother whatsoever. This also isnt the first time the mother has done this she's done this before when he (the uke) was living abroad and the only friend that he made there was also working for her and keeping tabs on him. He found out about that though but he didn't know about the whole tutor working for the mother thing. The seme DID NOT harbor any romantic feelings for the uke when he was a teen. I'm seeing a lot of comments saying that it's creepy that he was like introduced to him or something like that when he was a teenager but he did not like him romantically that way at all he was very focused on tutoring him and he kept it extremely professional even when he was confessed to by the uke. He actually left for military service after that.
