During our meeting, Kevin requested a song from this animated movie "kimi no nawa". I was intrigued because he was very excited to use that for their wedding. So I watched the movie and it was a tear jerker. A movie about searching for the person that you thought you already met. Holding feelings for someone you thought you knew. (If you haven't watched it, you should find time to do so)
Just like the movie, Abby and Kevin's meeting is not a mere coincidence. It is a product of series of events. They could have been worlds apart, but they met. Everything just fell into place.
