Summary
Grillby wants nothing more than to celebrate the perfect Valentine's Day with his husband. It's only what Gaster deserves, after all. Unfortunately, things are rarely that simple, especially when he wakes up with old, sour misery aching in his chest. One series of failures later and he's left starkly reminded of how flawed and simple and boring he is in the light of Gaster's glory. Gaster can't take that feeling from him, but he can, at the very least, make it easier to bear.
(And that's exactly what he plans to do, once Grillby stops being so stubborn.)

Summary
Dr. Gaster is the happiest monster on earth. He’s got a fantastic job, a cozy house, food and friends aplenty, and the world’s most loving soulmate—then he's turned into a vampire, which, you know, kind of throws a wrench into his idyllic lifestyle. But he's going to make it work! Even if it means he has to suffer, he's not going to let his newfound needs hurt anyone around him. He's going to deal with this alone, because that's clearly what any mature and independent monster would do.
Leastways, that's the plan until Grillby finds out.

Summary
Gaster is beyond excited to finally visit Grillby’s club. He’s been wanting to for quite some time, but Grillby had always insisted the club was far too dangerous. Now that he’s actually here, Gaster’s starting to think that was just Grillby’s usual overprotectiveness talking. He doesn’t expect to be hurt at all!
…he certainly doesn’t expect that it’s going to be Grillby who hurts him.

Summary
When monsters break into the Core, Dr. Gaster is sent to defend it—it is, after all, one of the few things in the Underground the king values more than Gaster himself, and the consequences for failing to defend it are steep. Fortunately, Gaster isn’t fighting alone. Grillby’s much too stubborn to let him.

Summary
An ongoing series of oneshots, featuring most prominently: Gaster being a phenomenal father, Grillby being the absolute best unofficial stepdad, a trio of mischievous skeletons, two dorks in love, a few insecurities, a handful of maladaptive coping mechanisms, domestic fluff, and an overabundance of affection because that's all I'm physically capable of writing at any point ever.

Summary
Grillby is used to bullying Gaster into not overworking himself, and most of the time, Gaster is (grudgingly) grateful for it. But when the king wants a job done—well, that job had better be done, no matter how hard Gaster has to push himself. Needless to say, royal orders of that caliber piss Grillby off.

Summary
Gaster is a small god. Grillby had known that the moment he’d waltzed into the nightclub for the first time—he carried himself with the quiet confidence that so few monsters have. He walks with the manner of a monster who knows he’s going to get where he wants to be and need not do anything else to ensure he gets there. If someone gets in his way, he has only to give them a sharp word or a sour look to send them scurrying. If he’s in a particularly crass mood, he might resort to shoving, but Grillby is under no delusions that he needs to shove. If he wants his way through, he’ll have it, and he’ll have it with ease. Grillby's small god manages every inch of his universe with impeccable control.
Gods, but it’s fun to shake that control up, sometimes.

Summary
Ninety-nine percent of the time, Gaster isn’t a possessive person. He’s secure in the knowledge that no one would risk taking anything from him, nor presume to so much as brush against his possessions, without his explicit permission. One of the many perks, he supposes, of being the Royal Scientist.
The other one percent of the time, he’s at Grillby’s.

Summary
Five days. That’s how long Gaster has been gone, lost, missing in action—five days. That’s how long Asgore has been amassing troops to find him. That’s how long Toriel has been pleading with the humans for their Royal Scientist’s life, should he be found behind their lines. That’s how long Grillby has been running himself ragged, burning his way through battalions and barricades and bunkers.
The sixth day, Grillby finds him.
