I think she has an insect or something in her(not sure) in one chapter he give a monthly pill or so.
He gave her something at first that if she didn’t take a pill he provided once a month her heart would explode I can’t really explain it but after she was about to take that hit from him with the whole ye ling thing he gave her the antidote since he trusted her now even though she had been loyal since the white tiger incident he had to be sure since she was one of the people trying to kill him for the heir position in the beginning
I agree she’s a good one, BUT I really like how his main girl finally came around and flip on her bad girl switch! This series actually has very little romance or intimacy, yet he still has a harem of women ready to wreck shit for him!!
Yin Mei is honestly 10/10. Gu Chang-Ge never had to hide his personality from her or turn her into a slave. They really are just one of the same mind. Did he even try that hard to manipulate her? She just wants to do awful things with him.
