Corrupt story (Undertale oc story)

Greetings.
I would be happy if you read my story! It's always been a dream of mine to be part of something special. Now that you're reading this, you maybe wonder how the story goes! You can help me to make that dream come true in this cute story!

I know the start is a bit... rough... But I think you will like my little characters I made:

Cath- I mean Caro, a little sunshine who can play piano and has a tragic backgroundstory;
Jojo, a mysterious but aggressive character who I don't like but well...;
Jette, a little shy but nice character who can fight for her friends and justice!;
...These are the characters you will first meet. Oh, don't worry I'm in this story too!

I'm super excited for you to see my wonderful (not all but anyway) characters! I can tell already that you will like it -will you promise to like me the most?
Your beloved favorite, ???
