The Most Terrifying Wizard's Love Is Too Devoted

Synopsis

Condemned for treason on fabricated charges by the royal family, the saint Celica chose to seal herself away, fearing that the orphan Morte, whom she had rescued at the Demon King's castle, would be placed in danger once more. Ten years later—when Celica awakens from her long slumber, the person standing before her is Morte, who has grown into a completely different person from the boy she once knew! A romantic fantasy about an older, dark-attribute, doting partner and an innocent saint with an age reversal! https://www.cmoa.jp/title/342437/vol/4/
