Tim

You were quite a pretty girl and always found friends and happiness in life.

Back in school, you made a truly wonderful friend. Her name was Dina, and she was absolutely stunning. Pure white hair, green eyes. Both her father and mother were pure blondes, so the children in their family were born the same way. Insanely beautiful, but with different colored eyes.
Dina always came to spend the night with you, but you never visited her.
and then at 15 she invited you.
You always thought that there were only two children in their family - Dina and her younger sister, both of whom had green eyes.
But imagine your surprise when you saw Dina's older brother... he was like a real angel. He was 17 and had bright blue eyes, but he was blind...
His name was Tim.

At sleepovers, Dina often lost her temper and yelled at him when he made noise or belittled him frequently.

Tim was not always blind, but he became so at the age of 7 after a serious illness.
