The young couple Mizutori was very happy and joyful until the husband, being too focused on his work, neglected his wife and children, which led to a very serious consequence. It is true that losing your wife because of a friend is real. Having been close for a long time, the husband often invited his friend over to their house to play and discuss work. Unfortunately, this friend was extremely lewd, and whenever the husband was too busy working, he took the opportunity to seduce and lust after his wife due to his nature. Partly due to feeling neglected by her husband who no longer loved her as before, and partly because of her promiscuous nature, Mizutori’s wife easily allowed her husband's friend to do whatever he wanted, including having sexual relations. The husband suffered, working hard and struggling all for his wife and children, only to be cruelly betrayed by his best friend and his own wife.
