Talented pastry chef Liu Mei's career was ruined and her life was gloomy after she was diagnosed with type II diabetes. While hiking to relax, she met Chen Jingyuan, a business tycoon who was dying of hypoglycemia. At her wits' end, she made an astonishing decision: to use her high-sugar urine to smear the oral mucosa to save her life. Chen Jingyuan was moved by Liu Mei's determination and kindness and decided to invest in her to form a team to develop healthy desserts that are truly suitable for diabetics.
