i wouldn't use fun to describe it. it's kinda like a gritty teen drama but korean style so it isn't all that gritty, lol. it does have plenty of lighthearted moments, though. it's about a teen rock band filled with misfits trying to make it big. ofc there is a romance arch, but the part of that drama that rly shines is the relationship between the members of the band. tons of skinship and bromance so i'd definitely recommend it~
