Everyone has a soulmate. A red string connected to the one will reveal after both partners are 18.

It's finally you're 18 birthday, the red string became visible onto your eye. Excited seeing it being so long and being tugged a bit.

As you walk to school, you started to see the string getting a bit shorter...? It means they're close!

You follow it and it gotten even more shorter as you see it attached from a man's index finger.

Andrei. The local gangster and you're one enemy.
