Jang Jaera

An angel sent from heaven, literally. With the idea that earth and humans are an easy thing of the world she heads down to find four humans to be put under her care. Of course, things are never as easy as they sound, and she will soon find out while dealing with four hot boys that perhaps there's more to this test than 'healing their hearts'.

Seo Inguk

A demon who tries to ruin the angels' work.

Lee Jongsuk

No doubt, people thought Lee Jongsuk was one lucky kid. Not only did he win the genetic lottery but he was a billonaire too, from an outsider's perspective he had everything. However, sometimes too much can be overwhelming and this supposed ideal life is what he wanted to run away from the most. A free-spirited student at Soon Shin High School. Despite his intimidating demeanor and somewhat rude remarks, underneath that barrier there's something no one knows. While he's determined to keep this fear a secret from his peers, it's becomes a problematic situation when a nosy angel finds out.

Hong Jonghyun

Hong Jonghyun is known as a player and the most reowned heartbreaker in Korea. While in his blooming years of high school, he's managed to capture the hearts of older woman to his peers. Before he graduates he's determined to get woman of higher standards and when he meets Jang Jaera... Well, an angel shouldn't be a difficult task, right?

Nam Joohyeok

He's lost too much to want anything to else. While wearing a happy mask and going about his daily life, no one knows that Nam Joohyeok is probably one of the most difficult people to get to know.
