Chu Chu, who ran away from a blind date, accidentally collided with Situ Wanqiu, who was three years younger than him and grew up in an orphanage and was about to go home. Situ Wanqiu accidentally pulled off the necklace left by Chu Chun's mother, which was the last relic of her mother. At first, he got angry and slapped Situ Wanqiu loudly, demanding compensation from Situ Wanqiu, but Situ Wanqiu was just an eighteen-year-old girl who had just grown up. The orphanage mother used all her abilities to make her what she is now. Although Situ Wanqiu worked hard to earn money every day, she really did not have the financial ability to compensate.

And just then when he returned from the distant United States... The real truth was slowly being revealed.
