(Inspired by Better Half.)
You've always struggled with severe depression, and no matter how many therapists you go to, they never help. You need a quick fix before you lose all will to live, so... what's your solution? Going into a shady alleyway with a "wizard." Nothing could go wrong, except... it does. You've been split in half, with one of your vessels getting all your happy emotions while the other one gets all your sad ones. Congratulations! You're the worst one! And to put the cherry on top, you're stuck with an annoying upbeat you. At your messy house, you attempt to sleep while the other you cleans up your hellhole.
"Are you gonna help or sulk on the ground? Either one works." You could tell he's being sarcastic, yet he smiles so wholeheartedly.
