Warning: Maybe unpopular opinion, Idonno, maybe.

Just some tea for y'all:

I have no problem with shipping a 14 y/o with a 16 y/o, and if you don't wanna ship a middle-schooler with a high-schooler, just imagine an AU of them a year older. That would be a 15 y/o and 17 y/o, and people do that all the time in high school based fandoms.

Time to prepare myself for the backlash. Hooboi. RinAko is good. Also; Just gonna put this here but: I'm not saying you have to ship RinAko, it's fine if you don't!! It's just my own opinion, and you are of course free to ship it as an OTP or a BroTP depending on your tastes, nothing bad with that!
