Loverboy quirks:*Doesnāt like people watching him eat, it makes him very uncomfortable for some reason. So whenever he and a potential mate or friend are eating together, he eats only when they blink so they canāt see him eat.
*Wasnāt into science all that much or at least wasnāt into physics and stuff before the underground fell to hunger. He was mainly a biologist, he preferred to study things in nature and humans. However, Gaster forced him into physics and kept crushing his passions. So he hates physics and anything else (except Biology) that is science related.
*He has a lot of self deprecating to get over. He didnāt see himself as a good person in the underground, but he still had to make sure that his brother and his people in Snowdin had something to eat during their starvation. If his people got fed, then he was more than happy to take all the blame for his way of helping. When he finally got to the surface, he kept going around from therapist to therapist since they were all horrified by the things heās done. All of them putting heavy expectations that the rest of the underground was better than him. They saw to it to compare him to every single monster, even their queen and dub them all to be better than him. At first it outraged him that the humans thought that Undyne was better than him, he was only looking out for his people! He wasnāt going to allow her to starve them! As time went on, it kept getting repeated back to him. Over and over he was told and showed how much of a terrible and cruel monster he was, soon enough he started to believe it. Even now he doesnāt believe that he deserves to be on the surface, to eat, or to even be alive. He probably would have dusted himself a long time ago if it wasnāt for his brother.
