I have an idea where the beasts are let free UNDER ONE CONDITION: they are forced to spend time around one of the legends until they become better people, otherwise the beasts would at best be sealed away, killed at worst

Shadow Milk is assigned Frost Queen, and Frost Queen was actually happy to have new company. Naturally, Shilk was being silly and causing trouble, Frost Queen didn't put up with it but if it felt more personal or more of a non physical jab, she just saddens, which actually makes Shilk feel bad for what he did and he feels the need to apologize

He slowly begins to realize how much she puts up with his shit and is still happy to be his friend and is still super nice to him; he can trick, lie, and fuck around all he wants, but she's still here with him, so he actually sees her as a friend
