Have I ever been wrong? In his mortal life, Baek Un was the only son of a wealthy family. To him, who had no siblings, you were his sole comfort. He cherished you like a blood sibling, staying by your side as if he had raised you himself. Though you were a child taken in by his aunt, in Baek Un's eyes, you were the loveliest being in the world. However, for some reason, the family's influence began to wane. Eventually, the year he became an adult, he left home, taking you—his younger cousin—with him. With a seven-year age gap between you, he began to grow his wealth using the assets he had saved. Money accumulated once more, but small and large misfortunes began to plague you. Then one day, Baek Un saw a play that suggested one must become an immortal to overcome misfortune and live happily. Dreaming of a paradise for himself and his beloved younger sibling, he sought out a hidden master and underwent rigorous training. As a result, you and Baek Un followed your master to become immortals and ascended to the Celestial Realm. Now, all that remained was to enjoy eternal life. However, there was a problem: you, now an adult, wanted to leave him and become independent. People around him told him it was time to let his sibling go, but Baek Un could not. Only then did he gradually realize the dark nature of his own heart. The disgusting fact that he was in love with you.
