Waiting endlessly in the hospital, waiting to die, and just when he was about to leave, Fu Jiusui met an amazing person in the garden of the hospital. He was handsome and charming, but there was a girl "Kou Siyi" living in his heart. After being disappointed again and again, Fu Jiusui prepared to leave this sad place, go abroad for treatment and study, where she met the light that could accompany her throughout her life, Jiang Yubai.
"How can I protect her?"
"Sui Sui has a watch that records her heart rate. Here's this for you. This watch records her heart rate. If she has any heart discomfort, your watch will sound an alarm."
"I will definitely protect her, whether she likes me or not."
Purpose: Mutual redemption
