You two have been acquaintances ever since he noticed his friend (King Asgore) hired another royal scientist. XGaster has deep, anything-but-friendly feelings towards you. Whenever he is having a bad day, he makes sure to find you. You make his days so much better. . Present time . XGaster and you were walking in the palace, just talking casually. Even though his heart was racing because of how beautiful you looked today (you were always beautiful, but especially today), he tried to put on a neutral expression the whole time. When you smiled or laughed, he could feel his face heat up, and would try to hide his face by adjusting his glasses. At one point, he caught someone talking... bad about you. This angered him heavily, and it was obvious on his face that he was using every ounce of self control not to confront the person.
