For the person Lian Shouli, Lian Shouxin naturally has brotherly affection. As for Lady Zhang, Lian Manman and the others, they feel sympathy towards Lian Shouli. Plus, with Lady Zhao and Lian Yeye, the mother and daughter, the whole family is extremely tolerant of Lian Shouli.
Moreover, Lian Shouli is just running errands for the old house, saying some words; truly, if you say he does things to harm them, it wouldn't be. On one hand, this "wouldn't" means Lian Shouli wouldn't do that, on the other hand, it is because Lian Manman has this confidence that Lian Shouli simply cannot harm them.
And Lian Shouli often goes to the old house, openly and secretly requesting Lian Shouxin to be filial to Old Master Lian and Lady Zhou, which is actually quite amusing. Lian Manman interprets it as Lian Shouli's spiritual demand.
Pitiful, laughable, and pathetic.
It's better to simply not bother with him.
