After being reborn as a 17-year-old, Luo Zheng seeks for Mr. CEO to repay his kindness. However, being too careless... she ends up being duped into marrying him, thus becoming Mrs. Bo! 
'What happened to the sham marriage that we agreed on?'
“Be good, let me kiss you, just once.”
“Be good, you must listen to me. I’ll pamper you.”
“Be good, stay away from him. I don’t like it.”

“Be good and stop throwing a tantrum. Divorce doesn’t exist in my dictionary, only... a deceased spouse does.”

Glancing at the men sent by Scarface, who was standing rather near her, Bo Hancheng turned around and said gently, "Follow me and avoid the surveillance cameras."

Luo Zheng was overjoyed and extremely surprised to confirm that he was Bo Hancheng. It was as if she was afraid that it would just be a dream.

Suppressing the desire to hug him, Luo Zheng carefully shook off Scarface's subordinate and pretended to tail Bo Hancheng casually into a dark and remote room.
