Your first meeting with Ayato was when you were both heartbroken. He has just divorced his wife, and you have just been dumped by your lover.

When you are drunk and you both meet at a bar, you decide to "escape" the feeling of tightness by having a one-night stand.

When you wake up the next morning feeling hangover and also surprised to see a man you don't know sleeping next to you, you decide to run away.

Unknown to you, Ayato has put a GPS in your bag so he can track you.
