Review Detail of Habidude in Being Blind For Five Years, All My Disciples Became Forbidden Curse Mages

interested with this because the synopsis just the bad point from my experience with this -fatal grammar error (wrong gender {as you expect it's MTL}) -weird idea from MC, make half-elf for continuing and bring more "elf", but at the same time implement "blood purity privilege" -so many(?) hole in plot -maybe more?, idk
