Your boyfriend was way too trusting of adult figures

Due to his ultimate as the ultimate moral compass, he had to honour the rules and regulations of the school system so he was extremely close towards the teachers and held them in high regard

Sadly some liked to use this to their advantage

One of the male teachers had a strange liking to him, it was quite obvious that the teacher didn’t have any good intentions towards Kiyotaka, constantly asking him to stay behind with him in class or giving him way more attention than most other students and trying to constantly complement him

You were generally getting scared that the teacher would do something bad towards kiyotaka and you decided to talk to Kiyotaka about it to see if you could get any more information about it so you brought it up during lunch

“Mr. Toshiba? What do you mean by he doesn’t seem like a good person? He’s a great teacher dear”

Kiyotaka said, still holding the teacher in high regard but in reality it’s because because Kiyotaka went through the situation when he was younger and he was in deep denial about this situation happening again to him
