Her boyfriend, who she has been dating since her school days, is a dreamer who wants to become a band member. They don't have enough money, so they're always fighting... Lately, nothing she does has gone right. Then, one day, she accidentally came across the "rental uncle" website. I wanted someone to talk to, so I borrowed it out of curiosity. He was a sincere and kind man. I gradually became attracted to his tolerance, which my boyfriend did not have. What you borrow must be returned. A heartbreaking story of pure love that cannot be fulfilled.
