I'm gonna feel so bad for this I'm so sorry Blueberry. This is gonna give me flashbacks I just want to make this for some reason.
Screaming, dust everywhere on her knife on her clothes Y/n had just finished all the monsters in the Ruins and was now moving on to Snowdin once she made it to Snowdin and met Us Papyrus, she put on her innocent face and wasn't covered in dust because she had showered. After he introduced himself to her, he teleported to his brother and gave him a warning about her. He knew something was off about her and he knew exactly what it was. (Probably gonna have tissues beside me just in case I start crying, oh the feels.) Blueberry didn't believe that Y/n was a bad person just like his brother's original self he believed in everyone. But that wasn't going to work on her she watched with an evil smirk making Blueberry feel uneasy. He hugged Y/n only to get stabbed. Blueberry turned to dust after saying "B-B-But st-still I believe in you!, y-you can do a little better even if you don't think so, I-I p-promise" after she had killed Blueberry she muttered "He was a cutie, yet he was stupid" twirling her knife in her hand she made her way to judgment hall. (And yes I'm skipping all the other parts because I don't want to type all that) dying a lot of times Y/n finally decided to reset and do pacifist plus because she missed the blue cutie. Clutching her chest in guilt she ran to a Blueberry and hugged him sobbing. Blueberry hugged back and patted her shoulder his brother had told him what she did to him last timeline. But he decided to give her another chance so Blueberry and Y/n remained friends but little did Blueberry know that Y/n had felt more for him ever since she had reset. Waking up with a yawn Y/n rubbed her eyes and got off her bed she lived with the skele-bros now and was happy about it. Gently knocking on Blueberry's door he opened but to see his friend Y/n blushing they sat on his bed so Y/n could tell him how she felt. Taking a deep breath Y/n said confessing her feelings "I love you Blue" Blueberry kissed Y/n's cheek and cuddled her close saying "I love you to"
