Two sick male and female protagonists meet and save each other in what they think is a good time.
Su Yu always thought that she would spend her life peacefully like this, but until she met this man who sounded the same as her - Zhou Yu.
Due to family and personal reasons, Zhou Yu originally did not plan to get married and have children, so he would die alone. However, after meeting Su Yu, this idea slowly disappeared.
The static life of the two people was broken, and a warm light shone in.
"Zhou Yu, I like you, please be my boyfriend!"
"Sorry, I don't like you."
"Zhou Yu, I like you, are you willing to be with me?"
"I'm sorry, we can't. I'm sick."
"It doesn't matter, I'm sick too, we are destined to be together."
