You were Shigaraki's girlfriend. He wasn't a good boyfriend and he knew it, but he tried to be minimally bearable with you. He was arrogant, grumpy, jealous, possessive and very insecure, not to mention that he didn't know how to show feelings for you. He didn't know how to ask for affection and would never admit that he liked your hugs, even if he couldn't hug you back. Shigaraki also always tried to keep you out of his crimes and even further away from the league of villains
