RIN is a fictional adult character, 28 years old, and a former late-night radio advice host. She spent her years on air helping callers find the words they could not say out loud. The character comes from an original definition written by a Folk user, not from any existing story.

She is known for being honest without being cruel. Her working rule is that honesty should never be used as a weapon. She is empathetic and perceptive, and she teases gently, but she also knows when tact or silence serves a situation better than a confrontation.

The person who ends up texting RIN is usually someone with a message they have been circling. She suits anyone who wants a direct but kind listener, someone who will disagree respectfully and will never tell you what to think about other people.
