It's because we readers see everyone's perspective but Hani can't so she isn't sure on how the brothers feel about her. In her perspective she isn't liked by the brothers and it's normal to be anxious by that. Hani has the most "human" character that's why I get why many people are getting irritated or mad at her.

I know you're suffering, but you could at least talk about all of this shit with your brothers.
It's annoying, that b*tch has no power there and you just don't go against her.
