Lately, due to the stress of work, I thought my wife deserved some special treatment, so I suggested she spend a relaxing day alone at a newly opened city hotel nearby. My wife, Kana, happily agreed and sent me photos showing her arrival. But after a while, she stopped sending pictures unless I asked, and when one finally arrived, a man's watch appeared in the frame. Seeing it filled me with shock and discomfort. Whose watch is it? What kind of relationship is hidden behind this? Despair and tangled emotions swirl inside me.
