Love spells, Safety kids, and fire demons

Part 1: Uh-oh

'This is a brilliant plan that couldn't possibly go wrong. A perfect, flawless, impeccable plan!' Tom thought to himself as he poured some marshmallows into the three mugs of hot cocoa. The young demon prince had planned this day out for a while, and so far, it has been going perfectly. Tom's master plan: get invited inside of Starships residence, (which he totally didnt achieve by begging and being a nuisance on the doorstep) gain a bit of trust with idle chitchat, make beverages and enchant it with a love spell. After the impeccable plan had been executed, Starship would be Tom's again. Nothing could ruin this! Nothing!! Except, something did. More like, someone.

"Hey, Star, I think my cocoa has more marshmallows, why don't we trade," Marco suggested, warily. He glanced at Tom, whom was sitting across from star and him. The spell works by having the spell caster and the object he wants the affection of both consumed whatever was enchanted. And, Tom, being so sure of his plan, had already taken a swig of his half of the enchanted drink, not expecting what was about to happen.

"Ooh, you're right, Marco! Gee," Star giggled, swapping cups with the boy, "Marshmallows are my favourite part of hot cocoa, too! Thanks!" She explained, Marco taking a suspicious sip. Everything was fine, except for the mildly horrified look on Tom's face, and the sudden strange feelings Marco had. And then the spell kicked in. There was a poof of pink, with small fluttery hearts, Star coughed, and the mist started to dissipate. "Whoa, what was thaaat?? Marco? Are you okay," she inquired, looking to her side at Marco once the strange, and kind of sickeningly sweet smelling mist had completely disappeared.
"Marco?" Star waved her hand in front of the Latino boy's face, taking a short second to process the look he wore. Star had an idea as to what had just happened, but was hoping that it wasn't the case. Well, that glimmer of hope was gone now, cause she knew that what she feared was exactly the case.
