Jihoon is the world-famous sunbaenim who has a legendary hallyu wave legacy, while Jieun is that successful hoobae whos been conquering the charts for years. They are also the worst hidden enemies within the kpop industry.As fate would have it, they have to complete an album together.Will it be World War 3, or will sparks fly? ForewordI was inspired to write a fic about two musicians who have a big age gap when I was watching My Lovely Girl. I actually didnt like the drama (poor script and I didnt think the FL suited the role), but I loooove Rain (theres no one like him in all of kpop, Im still convinced fight me haha) and I was thinking of a female musician who will be interesting to pair up with him and I thought of IU! Shes incredible and they are opposites, musically, so here we are.This is a slowburn fic, but expect twists and lots of fluff and romance too! This fic is entirely for entertainment, so I hope no one will take it seriously ^_^
