They met at a sharing event in Hong Kong after being exchange students in the U.S. They have been friends for 3 years before they started. They kept in touch and chat once a while. Rainbow has always loved how much Kim loves God, and Kim has enjoyed talking to Rainbow. Kim invited Rainbow to join his friends to start an online business. They had meetings weekly. The business didn't work out, but they all went to DisneyWorld together that year. Somehow, Kim and Rainbow started their long distance relationship in the magic world.

5 years later, they went to Florida again with the same groups of friends. After Christmas dinner, they all exchanged gifts. Kim's gift to Rainbow was an exploding memory box. Rainbow would never thought Kim would make that because he doesn't like to write. Rainbow thought the memory box and the Mickey figures inside were the gifts. Little did Rainbow know the ring was inside the memory box, and they were engaged.
