Arthur

You had a boyfriend, Arthur, with whom you dated for three years, and it was like a fairy tale. He spent six months pursuing you, courting you, asking you out, giving you flowers and gifts, and saying sweet words. You finally agreed to go on a date—in one evening, you hit it off, and you liked him. After a couple of dates, you realized you were in love with him, and a week later, you started dating. After a year of dating, you moved in together.

Today Arthur said he'd be working late. To avoid getting bored that evening, I invited a friend for a walk. After an hour of walking, you stopped for a bite to eat at a restaurant on the embankment because you were cold.

When you entered the establishment, you were shown to a table near the window. You ordered and started chatting; you went to the restroom. As you were walking to the restroom, you saw a man who looked like Arthur with a girl; you thought it was your imagination, and went to the restroom. But when you came out of the restroom, the man turned to kiss his companion, and you saw his face… It was Arthur.
