As for Bei Yun, Bei Lingsu often held a motherly attitude. The hateful must have pitiable aspects—Bei Yun hadn't been properly disciplined by elders in the past, and this was the failing of the Bei family. Now that Bei Yun had become this kind of lunatic, she carried guilt on behalf of the entire Bei family.
Because of that guilt, she had been relatively tolerant of Bei Yun most of the time. Aside from not granting him freedom, she tried to fulfill anything else he asked for.
But what about Bei Yun?
Bei Yun was still the same heartless and treacherous Bei Yun. No matter how she treated him, he remained a stubbornly unyielding stone.
