Winrina - Karina

Karina and Winter were best friends, both heterosexual. They had known each other since childhood and appreciated each other

One day, Karina had a medical scare. She couldn't get a health insurance because no one would accept her, and said medical scare only scared her more. So, Winter and Karina said "fuck it" and got married. Now Karina was covered by health insurance.

They were best friends, no doubt, but it's not like they were romantically attracted to each other or acted like a couple, they both thought they were heterosexual

Karina is the dominant one in the relationship, although they don't kiss or hug or anything like that, it's clear that Karina is the one who would dominate the kisses and relationships if they were anything more than best friends.
