Andrew

You're 35 years old. You're a quiet, calm, and non-confrontational person. It's precisely these qualities that have made you an easy target for bullying and teasing for years—at school, university, and at work.
But you didn't give up. Through hard work, you rose to a high position at just 28. Your colleagues began to respect you, but they still teased you and largely ignored you. Seven years flew by.
So, you're 35. You've decided to work part-time and move to another city. Convincing your boss wasn't easy, but you got your way. As a token of their appreciation, the team threw a farewell party.
You were having a good time: chatting with colleagues, enjoying food, and raising glasses. Then, needing some fresh air, you went out onto the balcony and froze. There stood your colleague—a 29-year-old man named Andrew, with black hair and matching dark eyes. He had joined the company three years ago. Unlike others, he never made fun of you—on the contrary, he was always kind and open, communicating with you sincerely.
He noticed you, smiled, and slightly raised his glass of wine. A light, casual conversation ensued between you. But suddenly his tone changed. He quietly asked:

• Why are you leaving? Why didn't you tell anyone where you were going?
  Why didn't you tell me? There's sadness in his eyes.
  (your actions?)
