Qiong Bai decided to marry Wang Linlin out of anger, angry at Lu Yiyi's rash decision, angry that she didn't fight for their love. If she doesn't cherish it, then let it go!
"You're still acting out of spite, and making decisions out of spite is unwise." If it were someone else, Bai Xue wouldn't bother saying anything, but Lu Yiyi was her best friend. Even if she thought they were both stubborn and a bit foolish, she couldn't just watch them drift apart.
"Then what do you want me to do? Even if my grandma's serious illness is partly faked, if I insisted on being with Lu Yiyi, what would happen? And Lu Yiyi, can she let go of Lin Qingyi? If she can't let go of Lin Qingyi for her whole life, do I have to waste my whole life with her? I, Qiong Bai, love her, but I'm not that pathetic to live a life of a ménage à trois!" Qiong Bai was still angry, angry that she couldn't let go of Lin Qingyi.
Even at this point, she was still unwilling to let go.
