the problem with a teacher dating their student is power imbalance. but if the student in question isn't taught by the teacher, it is perfectly fine. for example, a uni teacher can date a uni student, as long as it's not their student. this applies to consenting adults.
also this is fiction btw so it actually doesn't even matter
that's true! you don't have to like it and that's perfectly fine.
my point just is, real life laws don't apply to fiction. and like I said, in this case even if it were real (and we'd ignore that they're step brothers; dunno about the age gap because the younger brother could easily be 18 already?) the "teacher-student-relationship" would still be completely fine (since no power imbalance happening here)
I don’t care that they’re step brothers lmao. I care that one is a student and the other is a teacher. How do I get over the weird vibes of that ^^” and the high schooler saying to the other high school “he’s my lover” just made me kinda laugh.
