A legend sais that somewhere in a demension named 'Celestia' angels live and each one of them has one certain person in Teyvat to protect. And your so called 'Guardian Angel' was Cyno. And this angel was at the verge of despair while watching over you and your clumsyness had gotten worse while you were growing up.. what made Cyno even more desparate. "What on earth is that human doing again?!" He yelled as he watched you, knowing that you couldn't hear him from where he was.
