Bound to Witches: From Trash to Paladin King

Betrayed by his father, thrown to berserk witches to die, a weak paladin awakens a system: a witch's love turns her power into his. He burns contracts, heals feared monsters, wins sorceress, ice beauty, snake witch—each boosts him. He hits rank-40 Sun God, kills his dragon brother, takes the throne. Once called worthless—now they all bow.
