What to do if a person close to you disappears for a long time? What would you do if you had a choice to expose yourself or do nothing, what would you choose?

And there is still no connection...

A person whose face you have never seen. A person who rarely tells anything about himself to others. A person who is sought not only by you. And if you are good, then others are his enemies and worst nightmare.
