Before the day of their wedding, Chen Rui received a message from the Bloodmoon association concerning a mission. The mission was about killing Jin Mingze.
Of course, she was surprised by it. She has never thought of killing him even if they weren't close.
If she rejected the mission, someone else would be taking it from her so she really didn't know what to do. Jin Mingze was her best friend's brother so, in the end, she couldn't bring herself to kill him.
She decided to continue on with the wedding. Since she needed Jin Mingze to be alive, she decided to reject the mission. If someone was going to come after him then she would just discuss things with whoever that person was.
They never shared a bed and instead, they slept in different rooms during their first week of being a married couple.
Jin Mingze never touched her without her permission until one night, he came home, drunk and because of that, he entered her room and slept with her.
