I have no more patience for this and will move on to another manhwa instead. Because i feel like the little brother is mc's real little sister or someone from his original world who knows the sunbae and the novel. The little brother really tried his best to tell mc TWICE. But mc unnecessarily cut him off and probably make things harder for himself. The author probably write it like that just for the plot
All i remember:
-alpha ml's dad confined the mom (probably male omega)
-one day the ml give his mom a gun to "free" him
