Shin/Relationships

Gugu
Shin and Gugu used to be very close as brothers, but one day, Shin betrayed Gugu by taking all their savings and leaving Gugu to fend for himself. The two meet again in an alleyway when Shin is thrown out of a door and lays on the ground, seemingly unconscious. Gugu gives him Rean's ring to help him live a better life, but he did not forgive him.

Four years later, Shin comes to Booze Man's shop to meet Gugu again. Shin tries his best to make up with Gugu, promising him to earn enough money to build a big house and live together like they did before, but Gugu isn't interested. Despite Gugu's anger, Shin wants to prove that he's his brother and promises Gugu that, if he ever needed any help, he would be there for him.

In Gugu's vision of paradise, Shin carries him on his back. This proves that, despite his anger towards his brother, Gugu wanted to make peace with him.

Mister
Shin and Gugu used to work for this farmer. Not much is known about their relationship, but from the way they interact with one another, it can be concluded that the brothers were trusted and well-liked workers.
