Looking for a story I can’t remember the name off

I’m pretty sure it was a manga (but it could’ve been a webtoon) about this guy who often would listen to this radio show and had become kinda obsessed with it.. Somewhere along story he meets this random guy and they somehow lead to taking about the radio show and the main guy starts fanboying about the person behind the show (what do you call people who host/do things on the radio, radio personalities???) and we find out that the random. guys was the host guy
