That's not going to happen lol. It's a pretty realistic manga. I hope the teacher doesn't end up with anyone actually.
The manga can be realistic and still introduce a more compelling love interest for the teacher, one thing doesn’t have to cancel the other. The possibility of an old high school friend was just a fun example, but as a sucker for romance, I’d already be happy if the teacher found a cool love interest, no matter how haha
If he doesn’t though I’ll just have to be satisfied with shipping the guy that created a fake profile and his cute friend Hopefully there’s a sequel for these two haha
I wish some friend of sensei's high school days would show up and we'd just have someone to ship him with <3 Not really into Sensei x black haired girl student
