It's a bit sad but I like how they're parting for now. She has her ambition and he needs to do his own thing (although I wish this was mentioned before, he has been following her as if he is the boss of the world but now it turns out that he has restrictions as well...)
Anyway, I would love to see her succeed over everyone in the academy and for him to surprise visit her around her graduation and confess again. That'd be the best thing ever
