You growled at the skeleton before some more monsters rushed in. "Sans! Put your gun down!" A goat women ordered. "Y..Yeah! I..I..I bet she was just trying to s..save (b/n)!" A small dino lady added. "May I remind you that (b/n) stole information?" Sans said.

"Its not like he had a choice." You growled before Sans pressed the gun to the side of your head. "SANS! IM SURE WE CAN WORK SOMETHING OUT!" That's when your brother gripped his side and whimpered. You perked and wrapped your arms around him to support his weight.

"If you mind, we'll be leaving." You stated before Sans chuckled. "I'd like to see you try." Sans said before you punched his jaw and pulled out your pistol. You shot two bullets towards the others before they ducked. You and (b/n) bolted out. You heard footsteps before (b/n) fell.

"BRO!" You raced to him and helped him up. He was on his knees before you heard a gun click. You felt (b/n) grip your l arm before the bullet missed you both. "Sans! That's enough." You both looked to see a skeleton, maybe taller than Papyrus, holding Sans's arm down.

You leaned against the doorway as (b/n) rested in his bed. You both have been with the monster mafia for a few months now and you warmed up to almost everyone. Sans and Undyne were still a work in progress.

Gaster walked by as you sighed and closed the door. "Hello (y/n)." You perked before seeing it was just Gaster. "Oh hello." You greeted. "Are you alright?" Gaster asked. You looked at (b/n)'s door before Gaster got the message. "Ah. I see. I understand."

You turned to Gaster with a confused look. "I feel that way whenever Sans or Papyrus get wounded and they need to rest." Gaster explained. You nodded before Gaster started to blush purple a little bit. "I... actually came here to tell you something." You perked before Gaster nervously pulled at his shirt collar.

"(Y/n)... I... I have been having... some feelings towards you and-" Aww! He's being shy! How cute! You stood on your toes and kissed him. Gaster's face went bright purplr beforr you pulled away and smiled. "I love you too G." You said before walking away.

"Oh. Hey Emily." You greeted before highfiving Emily as you passed her. She returned the highfive before seeing Gaster blushing. "Gaster? You ok?" Emily asked. Gaster was silent before Emily turned to see you almost ready to round a corner. "Ooooooh." Emily said as she smirked.

"Fell for the spy, I see!"

"Shut up Em."
