As far as i understand The teacher is protective over him because of the family like bond they share and is acting like a protective big brother/father, and that's why he passed out too when he saw them kissing?
Well from what I read from the next chapter raws I think the teacher likes him romantically as he leaned in to kiss him… ╥﹏╥
