Feeling her pumping heart on his skin, Li FuJin understood that there's fear inside Yu Yan's heart that makes him recall about the first time she bit him.
He gently kissed her again before he answered. "Since the day I told you that you bit me"
"Are you.. Will you... Kill me?" Yu Yan nervously asked while staring straight on his inexpressive eyes.
Although Li FuJin feel bad that Yu Yan tried to keep it from him, he still understood that she only found out the truth recently.
After all, he confirmed her awareness after hearing her small threats when she was crying under the quilt the day she came back after missing for a month.
Moreover, the fact that Yu Yan has a childish mentality, it is only understandable that she will feel afraid to tell the truth towards him after watching him killed a Gǎnrǎn the first time they meet.
