That includes Lu Weixi. She intentionally moved in with Qin Zhiyou to piss off Qin Zhigu.
But now, whether she succeeded in pissing him off or not was debatable, but she certainly managed to put herself in a tough spot. Qin Zhigu's room was right next to hers—it was constant interaction. Whenever Qin Zhiyou was around, things were bearable since he helped her avoid most awkward situations. But without him, she always felt uneasy.
She really didn't want to have any sort of relationship with Qin Zhigu anymore, good or bad. But Qin Zhigu and Qin Zhiyou were brothers, and even if Zhigu got married, he would still bring his wife back to the big house. It was just a giant pool of discomfort waiting to happen.
Also, at this point, Qin Zhizha and Qin Zhimei were already up. Downstairs in the dining room, Qin Zhizha was languidly eating his breakfast while yawning. Seeing Lu Weixi, he smiled, "Ayo, sister-in-law's up. Big brother's not here, only second brother is."
