Shen Rui was accidentally bound to the Yin and Yang survival system due to a car accident.
System: Hello host, I am the 16,425th ranked survival system in the world of Yin and Yang.
Shen Rui: Get out of here, who the hell is your host?
Shen Rui is the third son of the Shen Group. Gu Chenyu is the eldest son of the Gu Group. He especially dotes on his younger sister. Because Shen Rui saved his sister from being injured and went into the ICU, she wanted to thank him, so she took care of him for a year...
Later, they rented together, and Gu Chenyu fell in love with Shen Rui at some point and began to pursue her.
"I like you, just like a fish can't live without water and a cloud can't live without the sky. Just promise me."
