Characters:

Seokjin (Jin/Jinnie)- A clumsy angel who fell from clouds as he wasn't watching his steps. He fell to Earth and didn't know how to get back with his wings missing. He was given a message through a dream that he can only retrieve his wings and go back to heaven if he can fix the lives of two mortals. The kind-hearted fallen angel was more than happy to do it. Unfortunately for him, his expectations were too positive and the two proved to be hard. 

Kim Taehyung (Tae/ TaeTae)- A problematic teenager who was dropped out of high school recently because of his offenses. Bullying, vandalism, and playing too many pranks. The kid, however, was too cheerful for his own good, but SeokJin knew of the suppressed emotions beneath that smile. He, along with Jungkook, fell in love with SeokJin without knowing the other was an angel.

Jeon Jungkook (Kookie/ JungKookie)- A rebellious boy who listened to none. He couldn't accept the fact that his parents are divorcing so he shut himself off from the world. He was tempted to try smoking, drinking and other illegal stuff to prove to himself that he is fine by himself but the angel stopped him from doing something stupid.  He, along with Taehyung, fell in love with SeokJin without knowing the other was an angel.

Okay. Here's another story. And this whole thing was inspired by this.
