My husband and I were living happy days. A kind husband, a peaceful daily life... I never thought it would be betrayed. One day, I happened to glance at my husband's phone. There, I found a message from a woman named Rin saying, "Today was great too ♡," along with an unbelievable video. Losing my reason in anger, I stormed into this woman Rin's house.

And so, it escalated into a fierce battle of stealing each other's partners...
