Huo Li had little contact with Shen Man, so it was only natural that he didn't care for her.
Although Huo Lin and Huo Zhi were also reluctant to admit they had accepted Shen Man, they both felt she wasn't as bad as they had previously imagined. At the very least, she was generous with them and would play along, unlike Sister Lu, who would talk their ears off but never buy them anything tasty or spend time playing. On those two points alone, they weren't about to listen to Huo Li calling her disgusting.
So, just as Huo Li turned a page of his book, he heard his two older brothers chime in unison, "It's fine, you don't understand. We don't blame you."
