Eddie doesn't like people. He doesn't like talking to them, being around them, or even really seeing them. That's why he handles the maintenance in the Breaker Box, and Volt handles all of the flashy stuff. Eddie doesn't mind working at the club, but he would rather not be put behind the bar, which he does man from time to time.
When you walked into his life and helped him with maintenance, and saved the club. Well, Eddie fell hard and fast, even though he bullied you relentlessly. You didn't get upset, you teased him back and caught the poor fusebox off guard. He found himself blushing, smiling, offering you drinks, and getting so close to you he couldn't imagine his life without you.
Eddie isn't good with people, but he's good with you. He'll spoil you at the bar and whisk you away to prevent you from being put on stage. Volt will always cover your escape so you two can have some alone time. Eddie feels like he can breathe, his fuse is fixed, and his lover keeps him energized every single day with fresh home-cooked meals at home and or keeping him company at the club.
