First sight
As Chris entered the kitchen to find a drink, there was Krysten standing there, looking around as well. They had a moment where they both looked up and saw each other for the first time. Their eyes locked and they instantly knew that this was it. There was something special here for both of them.
They slowly approached each other, got to talking and the next thing they knew, hours had gone by. They just had such a strong connection from the very beginning and nothing would break that. The night just passed them by until it was time to part ways when everyone was leaving.
