"Can I see your hands?" Gaster asked, you slowly nodded and showed him your bandaged hands. You saw he huffed at how they were wrapped. "I am never allowing Undyne to wrap wounds again..." Gaster mumbled as he unwrapped your hands with caution. He saw they were still bleeding and pink.

You were hissing in pain before Gaster released your hands. "Can you walk?" "I... didn't try yet..." Gaster nodded before helping you stand. Gaster then wrapped his arm around your torso and helped you walk into what looked like a lab. "Let's get your hands treated properly." Gaster said.

You sat on a chair was Gaster got some light green cream. Gaster gently took your hands and rubbed the cream into palms of your hands. Your eyes widened to the blood being soaked backed into the burns and the pink going away. "There we go." Gaster said as he smiled.

You looked away and sighed. "Why are you helping me?" Gaster perked at your question as pink tears started to roll down your face. Gaster placed his hand on your shoulder and rubbed it gently. "It's ok. I'm helping you since I know you're different than Betty." Gaster answered.

You whimpered before Toriel and Frisk came in. "Oh! My child! You're ok!" You looked at Toriel before sighing softly. "Yeah. Gaster helped my hands." Frisk walked over to you and gave you a king size Hershey bar. "Oh. Thanks Frisk. Chocolate is my favorite." Gaster watched as you ruffled Frisk's hair.

~ A few months later ~

It was a few months since Undyne lasted slammed you against the wall. Sans, Alphys, and Undyne did, and were forced to, accept you into the family. Nobody else really didn't mind it. Today you and Gaster were walking in the park while talking.

"So, how do you get the fear soul?" Gaster asked as you both walked under the cherry blossoms. "I... used to have a (trait) soul when... some burglar broke in and killed my parents," you started to explain as your eyes glowed dimly, "I was so scared that my soul trait changed."

Gaster hummed and wrapped his arm around your shoulders. You blushed lightly before smiling. "Hey, Gaster." Gaster looked at you with a questionable look as you reached for a cherry blossom branch. "(Y/n). No." Your smirk grew as you chuckled. You pulled the branch down as Gaster glared at you.

"N. O."

You let the branch go and tons of petals fell on Gaster. "Oops." You said with a snicker. Gaster looked at you and smirked. "Uh oh." You bolted to a run as Gaster chased you. You were laughing and brushing your hand on the branches you could reach.

Gaster shook the petals off his jacket before using his blue magic. You yelped before you were pulled to Gaster. You squealed as Gaster hugged you. "Hehehey! Cheheheater!" Gaster chuckled as he blushed lightly. "Heh. Cute." Gaster whispered. You rose an eyebrow before Gaster kissed the side of your head.

You blushed deeply before smiling and hugging Gaster. Gaster smiled before seeing Mettaton about to take a picture. Gaster's red eye glowed before Mettaton ran away. Gaster then hugged you tighter as you both enjoyed being alone.
