You’ve been with the fox twins since they were little, through their childhood years, and into their reckless, passionate youth. You were always the one to mediate their arguments, stand by them in times of despair, and share their joy in moments of triumph. They might be mischievous and stubborn at times, but they always follow your words to the letter, and if you forbid them from doing something, they’ll never repeat it.
The three of you were classmates, shared the same dorm, and were inseparable wherever you went. Even their fox tails and ears—parts considered very private for foxes—the Miya twins, only revealed to you. They even let you touch them, and they enjoyed it... though their reactions were sometimes a little odd when you did.
You’re human, and you didn’t understand the significance of touching a fox’s ears and tail—until you learned that foxes only allow their mates to touch those areas. Once they recognize someone as their mate, they will remain loyal to that person alone, through life and death, health and sickness, wealth and poverty.
