[Traveling through the book + Marriage first, love later + Double cleansing + Sweet pet] Xu Mian, a social beast who has been exploited by overtime work all year round, accidentally wore the book and became a cannon fodder female supporting character in the book who is paranoid and ends miserably. Knowing the ending of the original work, she suddenly realized that she gave up her infatuation with the male protagonist and stayed away from the emotional line between the male and female protagonists. She just wanted to live by herself and fulfill her engagement, be a wife of a wealthy family who lived in luxury and enjoy happiness, and lived a stable life with wealth. Only her fiancé Fu Siyan frequently behaves abnormally. Xu Mian deliberately distanced herself and gave in, but the other party kept pressing closer and favoring her in every possible way, breaking her preset peaceful life at every turn. Xu Mian, who couldn't bear it any more, said frankly: "Go and accompany your Bai Yueguang as soon as possible. Stop pestering me." Fu Siyan raised his eyebrows and stared, his tone serious and determined: "The white moonlight that I miss in my heart is always right in front of me."
