You seriously asking to see 13/14 year olds bang? I mean, I won't entirely write it off- I feel like Miss Norio might potentially cross that line if she feels things lead in that direction... but still. They can't even marry at these ages, far as I'm aware. He has to be at least 18, and that's still a little over 4 years in-manga away. Not that they have to be married, but still, potential consequences if they're not careful would kinda complicate things with that in mind.
