She knew that PEI Munian was senior XI's good brother. At the same time, she also knew the reason why Pei Munian hated her in the beginning but agreed to be with her in the end.
It wasn't love, but returning the favor.
PEI Munian had never liked her from the beginning. He had always hated her, hated her for playing with his good brother, hated her for killing his good brother. Thus, when she pursued him, he learned from her, indifferently hanging her, letting her chase after him, letting her experience the suffering of not being able to love him. In the end, he only agreed to her because he wanted to abandon her when she was at her happiest, just like how she abandoned senior Xi back then.
Regarding senior XI's matter, she was indeed in the wrong. However, she had never toyed with senior XI's feelings and had never intentionally hurt her. Yet, PEI Munian had pushed all the blame onto her without even distinguishing right from wrong.
