Pretty interesting! His answer makes it sound like teen dating in Japan is simultaneously idolized and condemned. I wonder how a contradiction this glaring actually works without making everyone's heads spin. For example, does "the professor [who] endlessly talks about his first girlfriend and how she degraded with age" then try to punish his young students for enjoying what he once enjoyed?
I'd always wondered about the trope "if someone sees my panties I have to marry them". That Quora explanation really put it in context.
