Jiang Tong was a person who had no tomorrow. She was stuck in an endless loop, repeating the same day, 4th April of the year 2022. From the initial excitement up until despair, Jiang Tong had tried everything to escape. She killed herself countless times, using different methods, but she would always wake up on the day of 4th April 2022. To pass her unlimited time, she learned more than a thousand and three hundred skills. From languages, to shooting skills, culinary skills, performing arts, etc. Jiang Tong learned everything imaginable. She enjoyed the excitement and hotblooded fights brought about by wrestling; she enjoyed the speed and thrill brought about by car racing; the pleasure of seducing and tasting all kinds of handsome men; the therapeutic sensations of playing various instruments.

No matter how much trouble she got into, when it got to four in the morning, she would suddenly fall asleep and wake up on the morning of 4th April. Until… After countless trials and errors, she finally managed to bed Z City’s most dignified but also the weakest young master, Ji Lanzhou. Ji Lanzhou was the Ji family’s youngest young master. Due to his frail body, he was the apple of the Ji family’s eye. No one in Z City dared to mess with him. But Jiang Tong didn’t care because she would have to relive this day again tomorrow. Yet… When dawn came, Jiang Tong was shocked to find Ji Lanzhou sleeping on her bed when she opened her eyes. The man even looked pale from having overexerted himself. Jiang Tong was delighted! She looked at her phone, and the date showed 5th April, 2022! After five hundred years, more than a hundred and eighty days, she was finally out of the loop! Ji Lanzhou woke up to see Jiang Tong laughing and crying like a mad woman. He pursed his pale lips and said, “Liar.” Jiang Tong raised an eyebrow. “It was an accident, Sweetie. So now I have to run for my life.” Ji Lanzhou was baffled.
