I think they mean it in more that the red head and the mc have a sex only relationship and since the red head is blackmailing the mc into giving him blow job, theres nothing really romantic about it, like w love or hate. I wouldn't say they're friends since the mc lowkey hates the redhead and is tryna get over him w the black haired dude. Plus the mc is close w the mom as well, hence why it can be interpreted as a sort of brotherly like.

First off I wasn't arguing. I was explaining how the commenter could see it as a love or hate situation. Did u read what I said? I never said they were brothers or step brothers. If you can't see them as (step) brothers, then that's you - I also don't see them as that. But some people will, and that's why they're saying "ah it's similar to love or hate".
I stopped reading love or hate bc the main ended up with his “step brother”(the art was beautiful what a shame), and I’ll do exact same thing here if it goes through the same path..
