k'tya
A K'tya is a giant brain who won’t let you fail. They’re like a teacher, a friend, and a lifeline all in one.
My K'tya is my teacher. He’s also my friend. He’s also my lifeline.
She’s the K'tya of our class. We all passed because of her.
That K'tya just got me out of a test. I failed. He passed.
