Contract with Xiaofeng: Summoned by a Ditzy Sweetheart from the Start

I transmigrated as Xiao Feng, the Wind Demon, at the height of his powers. Just as I was about to tear apart the world that had imprisoned me, a sweet, airheaded girl summoned me with a contract full of loopholes. She treated me like a cool pet, feeding me cake and sharing her troubles with me. Her best friend, an empress reborn from the future, was always watching me as if I were a world-ending demon. When the world feared my power, and conspiracies threatened the girl who had contracted me, I just found it annoying and casually crushed the so-called powerful enemies. Until the day the real apocalypse arrived… My sweet, airheaded contractor took my hand and announced to the whole world: “Don’t be scared. My Xiao Feng… is just a little shy.” And I found myself wondering whether this tedious contract held an answer more precious than freedom.
