His many unusual experiences piqued her curiosity, and his kindness brought her a warmth she hadn’t known during the internship. A few months later, Zhang Xuan asked Li Tiantian to meet him. That was when she met his good friend, Liu Yuhang. Liu fell for Li Tiantian at first sight. He wanted to work up the courage to pursue her, only to discover she was already Zhang Xuan’s girlfriend.

Li Tiantian kindly tried to set up her roommate with Liu Yuhang, but this only strained her relationship with her roommate. After the young people weathered one emotional twist after another, Liu Yuhang found himself a girlfriend of his own, and eventually watched Li Tiantian and Zhang Xuan walk down the aisle. But after they married, Zhang Xuan lost everything through gambling and online loans, and Li Tiantian grew from a young girlfriend into the pillar supporting their family. Liu Yuhang offered help and encouragement, while their family stood by them. Together, they saved the unfortunate household. After his mother passed away, Zhang Xuan finally saw what mattered most in his life.
