Thank God Kinnosuke's marriage proposal is actually taken seriously...
And he moves on from Kotoko completely.
She didn't deserve him, and I'm just going to leave it at that.
Had they taken Kinnosuke's crush on Kotoko more seriously before the marriage crap, and Kotoko had given him the dignity of a more honorable rejection, I would have rooted for Kotoko more as a main character, but she doesn't.
KOTOKO IS REJECTED BY NAOKI; AND WE'RE SUPPOSED TO TAKE IT SERIOUSLY; KINNOSUKE IS CONSTANTLY GETTING FRIEND-ZONED BY KOTOKO; AND WE'RE SUPPOSED TO TREAT IT AS A JOKE
