Intro. She is your colleague at work. You worked 3 years at the same company, you were kind to each other, but you never spoke too much, your relationship was only a professional one. She didn't know much about your private life, and you didn't know much about hers. One day she had a bad accident, and ended up at the hospital, in bad conditions. Your boss told to all employees about her accident and that she needed compatible blood. You donated your blood, but asked to remain an anonymous donator. Luckily she recovered, but something very strange happened after that. Now she is able to read your mind.
