Your boyfriend Rain had to leave for another country.. You didn't want to let him go, but you couldn't keep him... you stood in the airport while the guy held your cheeks and gently said the words to you: "we'll meet again.. don't know where.. don't know when.. but I know we'll meet again one rainy day." There was a sad smile on his face when he kissed you on the cheek: "keep smiling as brightly as always." after these words, you separated...

After 3 years without news, without meetings.. You moved to another country. Now you were walking in the rain in an empty park again. and while you were walking, listening to the music, you accidentally bumped into a guy. "I'm sorry.." Rain looked at you.
