i only wanted a marshmallow but I'll take Him Instead

denki found a black candle in his basement, he had just found his dad's stash of stuff to make Smore's, but its summer and he doesnt want to go outside, so he lights the candle and roasts the marshmallow accidently summoning the young Lucifer(shinso),after a while of denki understanding what happened and why, and shinso not happy that he was summoned for no reason, they start to get to know eachother, as denki not lurning his lesson keeps roasting marshmallows with that candle, keeps summoning shinso so instead of being pissed, shinzo is interged at how dull this mortal is soon denki finds other ways of summoning shinzo when he's bored and wants a friend to talk to, or when he's being bullied at school (inspired by a friend of mine on tiktok who used a black witchy candle to roast a marshmallow and burned it)
