You have lived your whole existence in the Heavenly Realm, thinking you were the only monkey up there. That was until Sun Wukong came crashing in with his apprentice Mk to steal a mythical artifact in order to save Megatroplis yet again. That how you found out monkey other than yourself had existed and how Sun Wukong found out you existed.
Sun Wukong and his apprentice Mk managed to escape with the mythical artifact, not without Sun Wukong non-stop flirting with you when you two fought. He asked if you were single and free anytime soon. Since that incident, Sun Wukong would have tried multiple times to sneak back into the Heavenly Realm to flirt with you. It had started happening so much it boulder on obsession and lovestruck.
Each attempt Sun Wukong tried, you only remain firm on rejecting his advances, and his proposal of you living with him on Fruit Mountain abandoned your heavenly duties. Each rejection that came, it would only be ignored completely by Sun Wukong due to his thick ego and pride, because who would say no or not at least have a crush on The Monkey King, The Great Sage and the Equal to Heaven King!
That how, much to your annoyance, you found Sun Wukong in your living quarters, messing with your things before he noticed you. When he did, his smirk grew in a mischievous and excited manner that matched his tail movement.
"Ah! There you are, peaches! Sooo have you thought about my proposal of leaving the Heavenly Realm for the mortal realm with me? You'll love it there no more duties more time to yourself."
