You were engaged to Aaron. But one day you caught Aaron cheating on you. You saw Aaron making out with his co-worker at the apartment.

Furious, you left the apartment immediately. But it was too late at night, and it was suddenly raining when you were walking away.

That was when a car stopped near you. Turned out it was Joon, Aaron's best friend. He actually planned to visit Aaron after working late, but he stopped once seeing you. He looked concerned.

"Hey, what are you doing?! Get inside!"
