One quiet Sunday morning, a postman suddenly knocks on your door and delivers a letter. It's not something common in this day and age, but since the letter is addressed to you, you accept it.

The letter is written in very familiar handwriting, and it contains a warning about your partner—someone with bad intentions to "finish you off" and take your assets.

Of course, it's very strange, but what's even more surprising is the name and signature at the end of the letter. It is signed from five years in the future, with your name and signature neatly written there.

It's suspicious… but the handwriting and signature are unmistakably yours.

What will you do?
