His face was the face of a student, but his eyes had the cold gleam of the fanatic. They were so deep and thoughtful; the eyes of a man who is used to looking at death. Hoya.

The high school boy who excels in looks and brains. #1 student in school who is known for his extraordinary dancing skills, and of course, his handsome face. But, a dark and murderous personality lies deep within . Lee Howon.

Kim Hana met Lee Howon when she was in 2nd grade, same class and they sat right next to each other. They became close very easily since it was 2nd grade and they were both the top 2 students in the entire 2nd grade. Currently, Hana is #2 in the entire school, right behind Howon. Hana is the daughter of the owner of the #1 hospital in Seoul.

Jung Daehyun is Hoya’s best friend in the underground business. They’re close and often go on missions together.

One day, Hoya and Daehyun were given the mission to murder a high school girl by the name of Kim Hana. Hoya knew that Hana was being targeted for her father’s selfish doings. Daehyun, on the other hand, showed no empathy for the girl since he was sure she did something to be targeted.

A few weeks later, Hana went out to go to her dad’s hospital to visit the little children in the hospital. The moment Daehyun saw her, she held a strong resemblance to someone he holds very dear, his first love.

Hoya and Daehyun end up not being able to shoot Hana. Instead, they end up falling for her.

"What is the boundary between being friends and being lovers?" "Perhaps we'll only know once we've crossed it."
