A Ghost of the Past

Han Jisung is just your ordinary kid, trying to make it big in a small world. Living with one of his best friends, who he sometimes may or may not fight with, he does his best to write his songs and make a name for himself while working part-time at a music production rental shop.

Lee Minho is a lonely ghost with his 3 cat friends and a young boy who keeps him company. He spends his days wandering the city and eventually takes interest in a boy with a notebook who has been feeding his cat friends.

Hyunjin rooms with Jisung and models full time but on the side he is pining after a young university student who spends his morning in a local cafe where there is a very sweet baker that can get anyone to talk.

Changbin keeps tagging along with his friend to some local production store to make some fun music. While there they meet a 3rd kid with dreams just like theirs if not bigger
