Nate

Nate is your ex. You dated for three years. Then you realized you might not be right for each other and peacefully separated.

You missed Nate sometimes. And he missed you. But neither of you ever got around to writing to each other.
A year has passed since your breakup.
You're sitting in the office, working. A friend calls you, you answer, and she tells you Nate was in an accident. Your vision darkened. You found out which hospital he was in. And you went there. A few minutes later, you were already sitting in the hospital room, holding his hand. He was in a coma, but no one knew when he would wake up.
