Callisto Regulus Headcanons - Tumblr Posts

Okay, I am in love with your yandere!Penelope headcanons. It’s so easy to imagine both OG!Penny and Siyeon!Penelope in that scenario, they feel so in character, which can be super tricky to do so all the kudos and love to you! But that mention of Callisto got me wondering what sort of yandere he might be? Especially since Siyeon told him that she doesn’t like blood/death/violence in canon, so while he is yandere, he’s definitely toning it down for her. What would he be like if Penelope was also yandere? Have a great rest of your week!

Oh AWWWWWW thank you sm for loving my yandere! headcanons for her!! <333 And especially so for saying that they were in character instead of OOC I was kinda scared they might be ngl lololol And oooohhh, I suppose since we know he's yandere in canon I didn't think to make headcanons for him since he shows all the signs...but that's a very hot imagine...

Callisto's eyes were narrowed at the sight of Penelope fending off an overly eager suitor, his hands ached to wrap themselves around the man's throat.

How he wished he could just stride over without a care in the world, just as he used to in the past, and break the man's neck right in front of her- just to show her, he can.

But Penelope wasn't one for blood, nor violence, having used her gun to fight off the monsters but retched over the side of the boat after seeing an arm flying over the side, bone still showing from where it was hacked off.

Oddly enough, he sees Penelope side step the man's next attempt at touching her, making eye contact with him as he raises his eyebrows at her sudden sneer.

Why was she-

Oh.

His lips curled up into a deadly smile as he gave listless remarks to the gaggle of women that had surrounded him while he had been staring at Penelope in the corner.

For he could hear her heels clacking on the marble floor as she made her way over to him, could hear the snap of her fan opening and he finally makes eye contact with her again once more as the women visibly tremble before her arrogant glare.

"Excuse me, I must speak with his highness."

One of the less nervous ladies, a recent debutante, pipes up, "His highness is busy!" ignoring how Penelope was positively radiating death from her beautiful lacy red dress.

Callisto wanted nothing more than to claim her right then and there, to press his lips against her pale neck, to leave an etching of his teeth so everyone could see that she was taken, that she was his.

Penelope gives her a snide look before snapping her fan shut, smoothly stepping around the lady as the rest part before her like water. She's beside him now, proudly standing her ground, and she slips her hand into the crook of his arm that was already waiting for her move.

"I believe his highness is now preoccupied with me." Now buzz off- before I make mincemeat of you- is what she doesn't say aloud.

Ah, Callisto smothered his grin into his glove, leading her away and into the gardens before he presses her up against a pillar.

Her hands around his neck, her sweet moans in his ears as he hikes her leg up around his waist, pressing kisses up her chest and onto her lips, "Mine, mine, mine- all mine, Penelope."

And she returns his love in full, her eyes darken, locking onto a peeping lady in the bushes as she presses against him harder, her nails digging into his back as she licks up his ear. "Only ever yours... Callisto."
