You and Sans were having a good time in snowdin with Papyrus, Alphys, Asgore and everyone else. Until one day you were distant from Sans ever since you met "her", Sans went to investigate even though he didn't like to do them. He secretly following you to a beach that no one has seen in the underground it's like a secret paradise! He was suprised at first, but shook it off to focus. He started following you more until he stopped in his tracks and saw someone you were talking to Chara: "You're going up there and stopping that bitch! Do you understand me, human?"
