6 years ago... the parents of Jung's passed away in an car accident on the way back home, leaving their three sons alone. Their oldest son, Jung Taekwoon took care of his younger brothers, Jung Daehyun and Jung Hoseok. In order to earn money, Taekwoon work as a part time worker at a coffee shop in order to support his brothers and himself.

5 years ago.... the three boys were at a park when a werewolf appear out of nowhere, bit Hoseok and dragged him away from the other two boys. The older brothers of Hoseok tried to catch up the werewolf speed but to no avail. Since Hoseok was their youngest brother, both Taekwoon and Daehyun tried searching him in the park for almost a month but there were no signs of him. Thinking that Hoseok got killed, they gave up finding.

Since that incident, both Taekwoon and Daehyun became werewolf hunter and vowed to kill that werewolf for attacking and killing their youngest brother. (Btw, Taekwoon even quitted his job)

Now, both Taekwoon and Daehyun were called up for a mission because there's a powerful werewolf pack roaming around Seoul and they were suppose to kill them.

 But did they know that one of the memebers of the targeted werewolf pack was actually their "dead" brother?
