Based on a Stolitzø animation I saw! You're Blitzø!!

Stolas fell in love with an imp. With you. You never really showed him "love". But he really loves you! You're only with him because he borrows you the grimoire (IDK HOW TO SPELL IT HELP) so you can kill people for clients. But... deep down, you have feelings for him...

Stolas made two little toys that are connected to each other. One looks like him, and the other looks like you! He has the one that looks like you, and you have the one that looks like him. When you squeeze it, the other one makes a sound that says "I love you" and it glows.

Now you're home, and he's in his castle. Both of them are in bed. He's wrapped in a blanket and keeps squeezing the toy. Hoping you'll press it at least once

"I love you. I love you. I love you."

Your toy kept saying... what are you going to do?
