Always was genocidal and she always will be, Y/n never planned to change her ways including for when she fell into the Au Underswap, killing everyone, dust on her hands, clothes and her knife she didn't trust anyone not even Blue. He was trying to help her change her ways but she didn't listen and kept killing him but then she felt something, it was regret. Resetting for the 20th time, meeting Papyrus and his brother who still slightly had a memory of her for some odd reason. Her words to Papyrus and Blueberry as a bone went through her chest were "I'm... sorry for everything.." Blueberry healed Y/n and hugged her tightly forgiving her as he kissed her forehead. Y/n looked at him confused only to get threw to the ground by Papyrus who grabbed Blueberry's hand dragging him to the house away from Y/n. Sighing she went to her house in Hotland not wanting to be bothered. Playing with her knife she pricked her finger with it hissing in pain she brought out her soul and cracked it on her own, eyes closing she fell to the floor. Blueberry went to Hotland to check on Y/n, knocking on her door and not receiving an answer made him worried. Opening the door on his own only to gasp at Y/n on the ground eyes were closed but she surprisingly was still breathing. Blueberry took her soul and healed it crying a bit. He loved Y/n even though she killed him in some many timelines he would still forgive her. Getting her awake he hugged and kissed Y/n making her blush and hug back. He took her back to the house to keep an eye on Y/n, Blueberry took away her knife as well so that she wouldn't try to harm others or herself, cuddling her they watched tv, and ate tacos that Y/n helped him make. Blueberry would always love Y/n and she would always love him. Blueberry and Y/n made tacos together again and Papyrus ate with them, trusting Y/n again, making Blue happy. That's all they wanted was for Blueberry to be happy and that's what they got. Hugging the two skeletons, Y/n kissed their skulls before yawning and falling asleep on Blueberry's lap. The next morning Y/n got up to the smell of pancakes, smiling she got up from the couch and stretched. Going to the kitchen to see Blueberry cooking pancakes for her, noticing her, he smiled and handed her a plate of pancakes. Which she gladly took and ate with him, they went on dates and always hugged each other after their dates, all of them were happy.
