Until a teenage girl called YN saw Sans sitting on the chair by the bar chatting with a friend about his day. YN starts to walk up towards Sans, and she said " hey it's nice to meet you Sans" but then he turned around as he said to her "do I know you ?". In response she told him "no you don't because you never met me before Sans" then went on " so how did you know me then?" he said to YN. YN said to him "I have been watching you and your brother Papyrus spending a lot of time together" But then she asked sans if he could take her back to his brother house so she can stay with them forever.  Then YN said to him "thank you! Sans" as he told her "you are very welcome". So he decided to take her back to his house for the night.  When Sans opened the front door they both walked into the house, Sans saw his brother Papyrus walk out from the kitchen. As he hugged Sans and Sans said "I'm so glad that you are safe". Sans looks at his brother as he said "is it ok for YN to spend the night on the couch?". His brother looked at him and said "yes of course she can spend the night here on the couch". Sans, fell asleep on the spare sofa. So papyrus decided to take YN upstairs into the spare bedroom as she said, to papyrus thank you for letting me stay here for the night I really I appreciate it and then papyrus said no problem as he walked out of the room and closed the door behind him slightly, as she realized that sans was so cute and sweet for letting her stay for the night at there house, but then she got into bed and fell asleep with the blanket over her. and the next morning she woke up and struggled to get out of bed, as she went downstairs into the kitchen to make herself some scramble on Toast for breakfast.
