Gaster AU x Reader ONESHOTS

Undernovela x Assassin! Hurt! Reader

You are a trained assassin. Your only job was to protect your boss's bratty son Randy. You always wore a cross around your neck to remind you of your mother and father. Today you were waiting on your motorcycle for the little demon since you had to drive him school.

"Randy! Hurry up!" You ordered with a growl, you heard Randy mumbling what you said before he walked out with the bullet proof vest and his very dull school uniform on. "I could give you a head shot, but I'd get fired." You said as Randy got his helmet on.

"Just take me to school." Randy barked back as he hopped onto the motorcycle. You rolled your eyes and started to take Randy to school. You didn't see someone about to shoot at Randy until you heard a grunt. "(Y/N)!" Randy exclaimed, you screamed and flew off the motorcycle as your hand was shot.

You saw who shot you, Asgore. "RANDY! RUN! NOW!" You ordered as you pulled out your flintlock pistol. You tried to shoot Asgore with your (bad hand) hand as Randy tore off his vest and helmet to run. You scrambled up to run with Randy.

- 2 hours later -

Your (good hand) hand was bandaged unprofessionally as you waved bye to Randy. You got him to school on time while caring for your hand, go you. You sighed before starting to walk to your church. It was mostly a monster church and humans did shun you for it.

But you didn't care. You were technically a skeleton in their eye... sockets. You also had a little crush on the priest. He helped you when you lost your parents, your old job, and basically your life. You used your (bad hand) hand to open the church door.

Gaster looked like he was just about done giving a prayer before he stood up and turned around to see you. "Ah, (y/n), this is a surprise." Gaster said kindly as he walked to you, you smiled and rose your shoulders up a bit. "Yeah. I'm here. Just... need help."

You showed Gaster your bandaged hand before wincing at how you positioned it. "How did this happen?" "Ambush. I was on my motorcycle." Gaster led you to what you thought was his room. "Let me see." You held your hand out before Gaster gently and carefully unwrapped the bandages.

Gaster then asked about the bullet, you told him that you already got it out. Gaster then treated the wound properly and used special bandages to wrap the wound. You held your hand as a small blush heated up your face. "Th..thank you Gaster... I wish I could repay you..."

Gaster just stared at you. 'Why must God punish me with (y/n)'s looks?' Gaster asked himself as you tilted your head in confusion. "Gaster? A..are you ok?" You asked as you looked straight at Gaster. Gaster slowly lifted his hand to the back of your ear.

Your blush brightened by the second. Gaster then tilted your head so your neck was straight. You were in such shock that you couldn't even think right now. "Please forgive me for this." Before you could ask what he meant, Gaster captured your lips in a kiss.

Your cheeks were a deep cranberry as you kissed back. Now, you had no idea if this was a sin or not, but you weren't wanting to find out soon. You eventually pulled away for the need of air before looking at the time. "Oh jeez! I-I need to pick up Randy soon!".

Gaster smiled and kissed your head gently. "I'm going to guess you enjoyed that?" Gaster asked with a smile, you nodded slowly to the question. "Would you like to be my girlfriend?" You smiled and nodded condendetly to the question. Gaster smiled again and looked at your bandaged hand.

Gaster gently held the bandaged hand and pressed his forehead to the side of your head. You snickered at the touch and childness before smiling.

Extra:

Randy and Emily (Author-Chan) were watching before Randy civered his mouth to hide his snickers. "I always knew she liked him!" Randy whispered, Emily nodded silently before starting to think. "Would this be a sin?" Emily whispered, Randy thought for a minute and shrugged.

"If it is, than (y/n) is Gaster's scarlett letter."

"Amen to that."
