Gu Baibai spent 2 years playing Qin Heng's perfect lover. When everyone believed that she loved Qin Heng hopelessly, only she knew that she just wanted to prove that she was "dedicated to love."
Xiang Qingyang knew that Gu Baibai was not a "traditional" good woman, she was blatantly bad and wantonly "showing her teeth and claws", but he liked it, and he allowed Gu Baibai to exercise his girlfriend's privileges around him as Qin Heng's girlfriend.
It's just someone else's girlfriend, just grab it.
