Somehow, I don't get Rinnosuke x Yukari. While I'm not a fan of Rinnosuke x Marisa, that one is at least understandable.

Rinnosuke and Yukari do have a connection in canon, so that's where most of the popularity comes from. Also their roles as 2 of the most mature character's helps.

Uh no.

Actually pretty cute for the het that it is. Never would've thought of this pairing but it makes an odd bit of sense (relatively). Way prefer it to RinnoMarisa, which comes off a bit pervy old man-ish. (The only acceptable age gaps go the other way, like here! lmfao) IDK though maybe Rinn/Mari hits better if you've actually read the COLAs, still need to get to them.
