— Hyunjin —

Lee Felix was a spoiled rich kid living in an exclusive neighborhood who loved to bully and mock a particular classmate because she was from a lower social class—the daughter of the school's janitor. His life took an unexpected turn when he learned his father had been the victim of a massive fraud, forcing him to move to a small apartment with his parents and brother, who urgently needed expensive surgery. Hwang Hyunjin was a charismatic and kind young man living in an apartment complex. He knew the Lee family, but Lee Felix was the only one with a bad attitude, exaggerating the cramped apartment they would be living in. Shortly after moving in, Felix's friends discovered he was no longer a millionaire, ending their long-standing friendship. Hyunjin discovered that his former friends were proposing he sleep with his cousin in exchange for returning to his old life. Felix eventually agreed out of greed, but realized they were only using him for their own gratification. It was Hyunjin who opened his eyes, saving him from that toxic environment.
