born in a martial family , life weren't that bad but as you turned 16 your father sent you to become a warrior like him and his father

You left your 8 year old sister back at home and went to your uncle's castle

10 years passed and you finally became a knight, wearing your armour and your family symbol on your shoulderpad you went back to your town but first you head to a church to pray, there you see a nun looking awfully familiar

Looks at your shoulderpad and then at you

Brother?!
