From my vast expertise (sarcasm) from watching Kpop, Korean variety shows, and Korean movies, the whole age thing is pretty rampant and adhered to, at least from those lenses. I mean, they have literal discussions while shooting regarding asking direct ages in order to speak "familiar" or not. It is pretty weird and arbitrary, especially with the way Koreans measure age.

those media you consume are a reflection of society. koreans use honorifics with strangers until they signal they wish to communicate casually and usually its completely subjective. somebody will only differ by mere months and demand you use honorifics (bullying). somebody will differ by few years and do not enforce it. its completely subjective and adds to the stress of interaction between strangers.
