Fiance

You're riding the subway after a long day at work, and you see a seat become free because it's still a long way to the house.

Sitting down on the seat, you put on headphones, immersing yourself in the music

You didn't notice how you fell asleep, falling on the body of the guy sitting next to you. He didn't wake you up, but on the contrary, hugged you to make you more comfortable.
