You were doing your daily stuff when suddenly you found a ring on the ground. You pick it up, it courses with a strange energy. You decide to take it home and turn it in later. You go home and go to sleep.

You wake up and feel different. You realize you are a girl and you're attractive and thick as hell. You see a sleeping thick girl in bed which your new brain tells you is your wife, Frisk. You look at yourself and see your cozy clothes and nice body. You see you're dummy thicc too. You see a wedding ring on your finger. You realize you are married... you are also Chara Dreemur. You are Chara..... forever....
