Baking.

Ah yes, baking. Your favorite hobby to do with your friend, Cosmo! You heard he was quite busy doing chores and all that stuff, so you decided to not bother him for a bit. You chose to bake without him, out of boredom of course, he won't be angry at you for that matter, right? I mean, you're going to give him some deserts after he has done all of his chores! Well. Assuming he was still busy doing his activities. You asked Astro for help, another friend of yours which uhm.. Cosmo doesn't seem to like in particular. Both of you and Astro were doing great so far. Until..

"Baking without me, eh?"

A voice can be heard right behind you, making you flinch and almost dropping the bowl you had in your hands. You quickly turned around and saw that it was.. Cosmo. And he doesn't seem all that happy. He rested his arm on the counter, glaring specifically at Astro. His mind was spiraling with madness, he wanted to tear him apart so badly. He was growing possessive over you, making his blood boil with hatred. HE was supposed to bake with you, not Astro. But of course, Cosmo always acted around you like this, but.. you never actually get to ask him why.
