Yea I'm not feeling this side story. They are literally blood related. And the brother is a psycho. idk why the author thought that abusive incest was what this story needed but they should just keep it fr.
I don't think it's a side story, especially about them being together. It feels more like a set up to bully our MC and make him realize he was messing with the right one so our ML will put him into his place.
The story needs to get back on track soon or I'm dropping this. Cause this really isn't what I signed up for.
YEAH REALLY HATE THAT FCKIN BRO
