Hey, it's Milly. She's always on my mind, but seeing how she's a fairly innocent person, she's not always apart of the demon shenanigans. In the few instances where she runs into Damion, he would be impressed with her taste in EDM and hard electronic music. Grunder can't process the tunes as well as Demion fucking with him by calling her his "ex".

For those who need context: Milly is the owner of the Hotel Grunder haunted for 100 years. She eventually convinces him to pass over, which is how he ends up in hell to be controlled by Demion. She would often use loud music to disturb the ghosts, as well as keep her comfortable. Grunder is never going to get used to it. By all accounts, they never dated either.
