He often has nightmares which are unclear at first but later reveal his memories of his mother and Hook who turns out to be his twin brother. We find out that Haru, like Hook, was born with heterochromia, but his eyes slowly became the same color as he grew older and lost his temper. At the end of the Webtoon, he turns into a wolf and his blue eye is revealed once more. It is once this happens that Haru is shot and bleeds to death in Hana’s arms.
Hook is Jeff's werewolf. He seems violent at first, but he is kind and does not want violence despite his occasionally harsh words. He acts out in violence because Jeff, his owner, beats and whips him, and forces him fight in an illegal fighting stadium, where people bet on the werewolf they think will win each fight. Hook's fighting name is Cerberus, and he is the reigning champion of the fights. It is later revealed that he is Haru's twin brother. Like Haru, he was born with heterochromia. Wolves with heterochromia are generally stronger and can be more ferocious. Knowing this, his mother pokes one of his eyes out in fear that he will be killed. Cause of death: fatal injuries.
