According to legend, those who are too obsessed can exchange their hearts for the ability to distort time and space. According to legend, there once was such a person. She traded her heart for the life of her beloved. According to legend, she violated the contract and made a knot against the will of heaven. She was cursed to be immortal and lonely forever... That winter, a girl ran out of a suburban community near the sea. She looked panicked, barefoot, and wore thin clothes. She turned around and hid in a shopping mall. A few hours later, a man in the city was looking around in a panic, and another man on the other end of the phone was waiting anxiously. "My girlfriend, I asked you to take care of me, why did she disappear?" "I didn't lie, I don't want to go back..." "Who am I, who are you, why did you save me, and then abandon me... I hate all of you..."... "I curse you, life after life, forever and ever, you will never get the one you love."
