Youngjae and Daehyun had known each other for years.

They'd been friends since they were born, they were best friends. 
Youngjae had always loved his friend, but he was so shy that he'd never told him.
When Daehyun met the love of his life, their friendship started to slowly fade away.

Himchan and Yongguk lived together. They were in the same college so they decided to share a little flat.
They had known each other for some time and they didn't have a job yet so they had to share some money and live together.
Yongguk was a playboy. He had a lot of girls, he brought them in their shared apartment and Himchan had to close his door shut and try to sleep when the man he loved was sleeping, nay having or whatever else, with some random s.

Jongup was new in town, he knew nobody there. 
The first day of school he bumped into a guy, Junhong, known as Zelo in the school, who yelled at him rudely.
He was the ''school bully'' that was what some new friends had told him.
But he wanted to know more about this guy, every time he saw him, he felt something in his chest... 
But Zelo was always a jerk to him.

One day Youngjae, Himchan and Jongup met a man. He gave them a four-leaf clover. It seemed a normal four-leaf clover but..
..after this meeting, their life changed.
