The idol childhood friend sucks, this manga is gonna devolve into some random drama about her getting picked up by some hot ikemen while she's on the job and then spend more time with him, while complaining that MC is abandoning her - when all he done is hang out with his friends. Then it's gonna be an uncomfortable back and forth of "I like them but I don't deserve them" BS, then the manga ends and they get together and 10 years in the future they're married when they should actually be divorced and hate each others guts
