A series of cute daring starco one-shots, suggested by you and written by me.

The monsters have been freed after being trapped underground for years. Frisk helped the monsters to make it out. They will tackle any problem that comes their way, but can the humans do the same? (Post-Genocide Pacifist, Female Frisk/Chara.)

Marinette traced her fingers down the smooth lines of the magazine, a blush creeping to her face. It wasn't just his toned, muscular body that set her aflame, although that was certainly a bonus. It was his eyes. The way his body appeared, languid like a summers day. His body said relax but his eyes said devour. She'd seen those eyes before...

Yet another series of random, cheesy one-shots. May contain a lot of Starco trashiness.

Sans died. But then he kind of un-died. Needless to say, everyone's confused, but Sans refuses to talk. Or maybe he just doesn't know? Rated T for mentions of torture and profanity and some possible trigger warnings.

AU where Star, instead of inhereting the royal magic wand at 14, unlocked shapeshifting powers. Chapter requests accepted.

Star and Marco are now 17 and their friendship hasn't changed. But when Star has a dream about kissing Marco, she'll soon find out her feelings are about to change. After an accident, Star leaves Marco alone and tries to forget about him. But the accident has Marco rethinking his feelings for Star. Does he like Star? And if he does, will he be able to tell her before it's too late?

Star will do everything in order to get what she wants, so Marco knew that there was no use keeping what he did a secret to her, so he also knew that there is no point on being annoyed to Star when she talks about her demon ex-boyfriend, Starco is just platonic after all.

What if your "best friend" turned you into her slave? Requests accepted. Cancelled.

Adrien looked over at the shy girl as she laughed and joked through their classes. Why wasn't she like that with him? Had he done something wrong, did he make her uncomfortable? Did he intimidate her? He wanted to hear her jokes too, he didn't understand what he had done wrong, but he was determined to fix it. He would get to know Marinette better, maybe then she would be at ease.
