✓ if your muse is/wants to be my muse’s friend:
Yes, he just needs to stop being a scared little shit.
✺ for our muses being snowed in together:
Mink is used to being snowed in every so often in his cabin so he'd know how to keep the place warm. He'd probably give Ruka a few of the spare blankets and park him in front of the fireplace with either a cup of coffee or hot cocoa to keep his hands warm.
✿ for my muse’s idea of the perfect date with yours
Since Ruka seems like a person that likes dogs, he'd probably take him to see the wolves. At a safe distance though so the pack doesn't see them as a threat, he might even get to see the pups if they go at the right time of year.
