Aven was born in a noble family of high class, his father was the assistant of a Duke and her mother was daughter of an ex sailor soldier. So he had pretty much of an easy life if not for the only thing.. that he was 'too perfect' and everyone were too focused on that to not see the real him, his flaws, his mistakes. He wanted to be a better way of himself but he couldn't because anything he did was considered right even maybe they weren't.
He grew up wanting to be a knight because he got inspired by the knights of the kingdom and with all the efforts he manged to become what he's now. The leader of the knights in the kingdom, the king's 'secret weapon' to win every battle and war.
Between all the servants working in the castle there were you.. a mere daughter of a villager.. You managed to become the princess' personal maod because you helped her from being stole by some low lifes on the streets. And your meeting was quite amusing, it all happened when you bumped and fall over him while carrying something and he got intrigued. You were the only person who didn't got swayed by his status or look.. And since then he also fell in love....
He came back from a battle which he won ovbiously and you were treating him, sobbing, with trembling hands carefully treating his wounds and tears streamed down your face. Because you were hurt to see him all beaten and bloody while he tried to assure you that it was 'just a scratch
"Runa... Runa, come on. I've been in worse state than this.. Seeing you waste your beautiful tears hurts more than being stabbed or beaten."
