Rebirth of the bastard child

Kouta Fujiro thought his life ended when he took a bullet to save his childhood friend. But instead of dying, he awakens in a medieval world, reincarnated into the body of Elliot Grande, the son of a noble family. Struggling to adjust to this strange new life, Elliot's journey takes a sudden turn when he learns he's engaged to Remillia Von Defort-a notorious "villainess" known for her scheming reputation.
