Liu Yisheng has always been a wild horse, until he fell in love with Xin Ran. Only he himself knew that in his straightforward life, there was one thing that he regretted so much that he couldn't sleep at night. In the eyes of relatives and friends, Xin Ran was a well-behaved, sensible, and polite boy since he was a child, until he later met Liu Yisheng. You ask him if he has ever been in pain or suffering? Of course there is. But I have never regretted it.
