Shin/Plot

Plot
Gugu ponders his identity, wondering why he is who he is and why he wasn't born into a rich family. Shin says that he often thinks about that as well, but reminds Gugu of their promise to work hard, earn money, and build a big house that they'll live in together. The next day, Shin and Gugu eagerly go to work.

After work, Gugu comes home from work and sees Shin talking to some shady men that Shin calls his "friends". Gugu notices that some of the money they saved up has gone missing from their savings box and asks Shin if his "friends" might have taken some, to which Shin responds that he shouldn't accuse them and that there isn't anything they could do about it now, so they should focus on just earning it back.

The next day, Gugu comes home to his brother as well as all the money savings missing. In the now empty box, there is note from Shin saying that he was going to "change his fate".

Several months after Gugu's accident, he comes across Shin in town getting thrown out of a business. Shin is passed out in an alley way, frail and on the verge of starvation. Gugu feels sorry for him despite his brother's betrayal and leaves the ring he received from Rean in Shin's hand. Just then, Shin awakens and calls out to Gugu, who answers with "I have no brother" and leaves.

4 years pass and Shin approaches Gugu at the Booze Shop. He tries to make small talk with Gugu, which angers him. He calls him out for abandoning and betraying him. Shin tries to reconcile using Rean's ring, showing his conviction of earning money on his own, when he could have easily sold the ring to lead a carefree life. He tells Gugu that he started his own farming business and now wants him to come live with him, but Gugu declines. Shin goes to say goodbye to Booze Man and tells him to return the ring to Gugu.

After the battle at Rean's mansion, Shin sees Gugu's body and cries. He and Fushi tell Booze Man and Pioran about Gugu's death together.
