Five years after marrying Kana, I finally take her on a long-awaited trip at her insistence. She is thrilled to arrive at a famous resort hotel, but even after check-in I keep prioritizing work, never realizing how lonely she feels. Left alone, Kana meets another man by the pool and spends time with him at the bar and casino. I only understand what has been happening when I witness an even more shocking scene at the night pool.
