I know this situation is supposed to be endearing, but it feels incredibly exploitive... Like, all that's happened thus far is that instead of being forced to do things for his sisters, he's being forced to do the same things for seven rando girls. He's legit just being used in the same way by different people, and now we're supposed to be all—aw wow, he's found people that understand him!
The only way I would be okay with this development is if they become a stand in for him to grow a fucking spine. He can tell them to back off without them exploding at him like we know the sisters would. So it's like doing what he should've done in the first place, but on easy mode since these seem like marginally better people.
But with the way the chapter ended, I am not hopeful that's going to happen at all... He's just gonna be a doormat for these people instead, wonderful.
