May Nothing But Death Do Us Part?

Here, enjoy.

"What if he doesn't actually want to marry me?" You yelled.

"(N-Name)-" Alphys tried to interrupt.

"What if he only wants to marry me so he can have a roady?" You cut her off.

"(Name), you punk-" It was Undyne this time.

"What if he only wants me to train the snails?" You cried once again.

"(Name), my child-" Toriel got cut off too.

"Ohmyglob, what if he just wants me to breed baby ghosts?" You began to cry and sat on the floor.

"(Name), babe. You're gonna get your dress dirty!" Sans held your hand and pulled you up.

"I'm sorry! It's just, I'm scared!" You confessed.

It was your wedding day and you were marrying Napstablook, the cutest little ghost in the Underground. Alphys had made him a robot body to resemble the sketches of what you always thought the ghost would look like in a human body so wearing a suit was slightly easier.

Undyne was your best friend and you got along well with Alphys because of that. Sans was like your brother (he was your brother Grillby's best friend) and Toriel was everyone's favourite goat mum and Frisk? Well Frisk was the first human you met but you loved them to death and often accompanied them to Ambassador meetings (carrying a fire extinguisher, human places tended to burn easier with your blue flame body).

"You'll be fine Punk. I'll pulverise the Jerk if he tries anything" Undyne reassured you, flexing her arms in the purple and black tulle dress your bridesmaids wore.

"Please don't. I don't want Mettaton being angry with you" You told her, giving Alphys a stern look who nodded back.

"Y-yeah. You'll s-spoil (Name)'s wedding" The lizard monster said, she too wearing a bridesmaid dress.

"Come on babe. Let's get you to Grillbz" Sans smiled at you and opened the door "I bet Napstablook is dead excited on his wedding day"

You glared at Sans as Frisk grabbed your hand, they were being the ring bearer and the flower child and seemed really excited. You noticed your big brother talking to Papyrus quietly and cleared your throat.

"Oh wowie! (Name) you look wonderful!" Papyrus exclaimed hugging you close.

"You look beautiful (nickname). Come on, are you ready?" Grillby asked you as he would be the one walking you down the aisle.

"She's smoking isn't she? Hey babe, if the ghost doesn't work out I'll be here so you don't get bonely" Sans joked, you glared at him, used to the joking flirty behaviour from him.

"Absolutely not" Grillby hissed as Sans laughed.

"Okay, Grillbz. I'm only trying to be funny, no need to make this heated"

"Sans! Shut up!" Papyrus yelled at his brother as everyone but you, Frisk and Grillby took their seats or stood in position.

Music was played and you began to shake, feeling your flames ignite higher through nerves. Grillby sensed your unease and linked his arm in yours as Frisk giggled and dropped some flower petals. You looked up to see Napstablook waiting for you with a smile on his face and Mettaton stood at his side (being the best man) and Alphys and Undyne on the other side, waiting for you. Finally, King Asgore waited patiently as he would be the one to officiate the marriage.

"Up you go, little sister" Your brother whispered and you grabbed Frisk's hand, leading them up with you so they could hand Asgore the rings and then go and sit with Toriel.

You glanced at Napstablook who looked as nervous as you felt.

"Hey" You whispered smiling.

"H-Hi (Nickname). You look so beautiful" He whispered back.

You blushed and nodded to Asgore who smiled and began.

"Do you, (Name), take Napstablook to be your monsterfully wedded husband?" He asked and you nodded.

"I do" You said.

"And do you, Napstablook, take (Name) to be your monsterfully wedded wife?" Asgore asked once again.

"O-of course I d-do" The ghost stuttered shyly.

"May you both be eternally happy, and may only death do you part" Asgore said and a snort escaped from your throat.

The king failed to see what was funny but you could see Napstablook and Mettaton had picked up on the reason.

"Urm, King Asgore sir. I'm, I'm already dead. Err, I'm a ghost" Napstablook muttered bashfully and Mettaton let out a loud laugh.

"Fine. May nothing but (Name)'s death do you part. You may kiss the bride" Asgore said, a smile on his face.

Napstablook had recovered from his initial shock and wrapped his arms around you and bent you both down, placing his robotic lips to your blue flame ones. Wolf whistles and claps were heard all around and you smiled into the kiss, wrapping your arms around your new husband. When you parted, the two of you were flushed and panting slightly but nonetheless, Napstablook scooped you up and walked down the aisle, carrying you bridal style.

"I love you (Nickname)" The ghost told you sincerely.

"I love you too, Blooky" You replied, leaning up and kissing him again.

You didn't notice all of your friends surround you until someone cleared their throat. You looked up to see Grillby glaring at the pair of you.

"Lighten up Grillbz. They've been dying to do this, just let them have fun. (Name)'ll stop before it gets too hot" Sans told his friend who groaned.

It seemed like the perfect ending to a perfect day...

"(Name) darling, please get off my cousin before you singe him. You can kiss as much as you want later, and even more if you feel like it. There will be a fire extinguisher in the suite you can use..."

"Oh no way. My baby sister is not doing it with a ghost yet"

"Fine, I'll wait till the honeymoon"

"(NAME)!"

Needless to say, the hotel rose in temperature that night, whether Grillby liked it or not...
