Why did Liu Shishi marry Wu Qilong, a has-been star who is 17 years older than her?

Wu Qilong, who was once brilliant, may have been Liu Shishi's idol since childhood. Although he has passed away, there are still some things that attract Liu Shishi, such as being handsome and eloquent. In addition, the two of them acted together in "Bu Bu Jing Xin", and they fell in love over time and came together.
