Perhaps just a good ending could be that Asterion is indeed released from his eternal torment and he and the MC just keep working in the hotel, which is what Asterion loves doing after all, but without any shackles. I dont know, like something simple, easy xD? Or maybe Hades offer us a choice? Keep working on the hotel but as a free mythical or banish the hotel and Asterion returns to the Hades? Which perhaps could also be a great chance to decide if we want to lose our life in exchange of following Asterion to the Hades? Or... just let him go?

Unlikely plot twist, Greta is actually Aphrodite :P? I mean, gods can take any shape they want. Right?
