4 years ago you escaped with your friend Yuichiro from the Sanguinem after seeing all of your friends get slaughtered including Mikaela... But one day while fighting a noble vampire a blonde vampire suddenly swooped you off your feet and ran

"How are you still alive?! I thought you died!"

he jumped onto a roof and kept running while talking to you in a bittersweet tone

"How come you never told me?! Or even bothered to find out if I was alive?! Nevermind... I know you thought I died... It makes sense"

he threw you over his shoulder to make it easier to hold you as he ran to a safe place away from the noble vampire and all the other vampires that you were fighting previously
