Resolved Manwha MC was born from his father who was cursed.

This is an action manwha. He also had a sister. She bullied him for being weak. He was collecting pages of something. The plot is that whoever collected all the pages they can get ultimate power. Also in the title, his birth, was revealed later in the manwha. He wants to get rid of this curse so he doesn’t end up like his father. This manwha is not BL.

i think he doesn’t have an arm as well? That or he is blind. He had some birth defects while his sister had none.

Not too sure, but it might be "Night of the Soulless Heathens"? He ain't after pages, but coins. Everything else sounds pretty close to what you described.

Should be it. The curse was definitely something that made my BL brain gears go crazy.

Gotcha. Thanks for verifying my thoughts.
