Custom story idea.

[Aloïs]

Hey guys this is my idea for a custom story and I wanted to know if it is any good and if it's not already done.
Story:
You just divorced from your wife and decided to go to a hotel. One night you drink a lot of alcohol to feel better and you pass out. You wake up in your hotel room. When you walk out everyone is gone and there is a bloodtrail leading to one of the rooms. You start to investigate what happened.
There will be two big story lines, one of your character and one of another guest. The one about the guest will reveal more about what happened.

I am thinking of letting the story of the geust be told by notes.

And could anyone tell me how I add subtitles?

Thanks you,
Aloïs
