Because she is
I like the webtoon because of the MC, but it's obviously patriarchal and capitalist agenda to push women and the working class (mostly women) to do all the Labour while men just cross their arms.
Those male characters are based on real life males where they purposely sabotage their tasks so women do all of it.
Think about the shitty husband who makes a mess to avoid Landry and cooking his own meals.

How can she work with them being like that?!?!? If it were me i would bomb the entire building i mean they don't even know how to do a simple ass work and always make out bruhh...ik this supposed to be comedy but, i just get the feeling. She literally overworking herself
