Summary
All that Ink knew was that one day, his dull reality of serving macchiatos and dealing with rude customers was changed forever when one particularly handsome skeleton entered his life and turned his world upside down, enchanting him with feelings he had never felt before. Does it really matter if Ink can't remember exactly how they first met? First meetings aren't always as memorable as romance books will have you believe.
After sneaking glances at him for months, Ink's feelings are suddenly reciprocated when Error asks him out on a date. What does someone do on a first date? Especially one who has never even so much as had a crush before? And what does one do when one's own... personal fantasies... keep invading their brain and confusing daydreams for reality?
Oh well, it'll be fine. Everyone gets first date jitters, don't they?

Summary
(desc too long for ao3 oops)
Undertale#297. Glitched, unstable, banned from ever being contacted by Multiversal visitors out of fear that it could get worse. But no one considered that the Sans within would reach out. It was rare for an AU to figure out AU travel by itself, after all.
And yet, Check figured it out. But to jump immediately into a Multiverse with no sure way back and no knowledge of its happenings? No, he had a proclivity towards impulsivity, but he wasn't an idiot. Measure once, check twice, after all. So he took his time. Figured out how to target the portals, learned how to return home, refined and slimmed his design down until it was handheld, and most of all, he learned the politics of the Multiverse.
But something about it didn't sit right with him. He'd been Dust and he'd been Killer, so why were Dust and Killer spreading "senseless" negativity? He didn't know, but honestly…he didn't care.
He saw his copies, and his only thoughts were those of mischief. It was an awful idea, and he'd definitely get hurt, but…
Well, a bit of harmless impersonation was always fun.
Or; Check travels universes for the lolz and indirectly stops an eons-long war by doing almost nothing

Summary
"Juniper..." Blueberror trails off. His brows knit together- deep in thought. He takes another sip. "I like that" For once, he doesn't meet Nightmare's gaze. "I-" he mumbles. "It- It would be a nice name. Juniper."
Nightmare steadies himself. How often had he been there to witness the birth of a new name? He takes a deep breath. Despite everything, he can recognize this for the honor it is. He can feel the power. It tastes like, well, juniper: clear and bright. Dark and shining.
Five times they talked about the nature of names, and the one time they didn't.

Summary
Ever since she was taken in by the three most popular girls in school, Iris's life had been a breeze. However, with the arrival of a new girl, one who seemed just as interested in her as she was, things might just go off the rails.
It's a Heathers Errorink AU, I dunno what to tell you. Read the tags, especially if you know nothing about Heathers. It is a (black) comedy and I'll probably try to hold true to that vibe but there certainly be dark things ahead.
