Y/n:"now that your smaller where are we?" Solaris softly started to laugh "what's so funny?" I ask completely confused

Solaris:"I thought you would've figured it out by now." Now I'm more confused

Y/n:"okay your confusing me, figured about what?" But what she said made my eyes widened

Solaris:"we are in your mind." She raised her power showing authority and how below I was in comparison to her "As one of the three supreme entities that lived and ruled the Dimensional Gap. I Solaris Cosmic Dragon Goddess of Peace and Chaos, have chosen you Y/n L/n to be my host, wielder of The Eye of Judgment and my mate"

Y/n:".....nani?"

Solaris:"congratulations young mortal!" She happily said

Intro:

================================

-Inside y/n mind-
*Nobody's pov*

Y/n:"wait wait wait, hold your pussy, what do you mean I'm your mate?!" Y/n was very confused first he learns that a giant dragon god lives inside his body but suprisingly it turns 'he' is a 'she' but the surprises didn't end there as it also turns out he is quote on quote "her new mate".

Solaris:"of course it does, you see us dragon gods decide who we choose as are host to bear our immense amount of power and if we enjoy being with are current we can judge if he/she exceeds our expectations then we deem them worthy of becoming are mate for all eternity." She said briefly explaining the situation he's on

Y/n sigh and pinch the bridge of his nose try to understand the small explanation

Y/n:"so your telling me you randomly choose some boy/girl and spend your entire life with them unless they exceed your expectations so you could mate with them in the end?! Is that what I'm hearing!?"

Solaris:"if you put it in that way yes, aren't you excited you can have your ways with a hot~sexy dragon goddess like me~" She said using the art of seduction on him but resulted unsuccessful with the boy

Y/n:"look I'm flattered for the offer your dragoness I maybe a bloody murderer at times but I don't enjoy a woman's body for lust and besides (with a smile) I already have two girls waiting for me."
