It's just like doting fathers who doesn't want to be apart from their "daughter" as per say, It's not that deep, it's just an overprotective parents, as an asian, I get this a lot since my sister's bf took like 3 years before he's seen as approved by my parents, I mean he's a good guy, but warming up to the parents aint easy. It's also like entrusting the one you've raised into another person

They knew Kana since he was in diapers. There is no "warming up" to him needed if he was not good enough, it would have been obvious since a long time ago. They had no problems with the two being close friends, but when romantic feelings are involved, Kana is suddenly not good enough to date? If he was such a bastard that they do not want him in a relationship with Ritsu, then he was too much of a bastard to be his friend in the first place. And yet...

this is so OA girl. if you’re not knowledgeable about asian parents/culture then just say that. and they weren’t even “freaking out”, the scenes were very obviously supposed to be taken light heartedly and in a joking manner, but ig you don’t have enough media literacy for that.
dating is very different than being friends, and i think it’d be stupid for parents to just accept whoever for their kids just bc they’ve known them for a long time. you’re taking this too deeply when ritsu’s parents didn’t even do anything like insulting kana-chan. and mind you, in those one-shots, kanaritsu are still HIGHSCHOOLERS. they’re barely legal and still need guidance from their parents.
TLDR: you’re making a problem out of NOTHING

Maybe you grow up to some parents who doesn't even care about their child that's why you're so bitter about a protective parents. Did they cross some boundaries like forbidding or telling them that they can't date? No, it's normal for parents to care and being protective of their children. Stop being bitter and find someone that will care about you cause clearly you don't have one
Ngl, I can't get over how weird the adults' reaction is to Ritsu and Kana liking eachother. They knew the kids since they were babies, watched them grow up, they know exactly what kind of people they are, yet they still act like Kana is some dirty old man who wants to take their daughter's virginity and then abandon her pregnant... Like, chill. Kana isn't a bastard in it just for the sex, and Ritsu is his own person, not to mention that he isn't even a girl, so some kind of misplaced misogynistic "she is weak and needs protection" isn't even aplicable here.
