Unable to bear the defenseless body of my childhood friend, who has become her sister-in-law, she crossed the line.

He moved to Tokyo and started a business, but failed and all he had to do was in debt. At a loss, when she ran away from home, she ran away from home, and was greeted by her sister-in-law Akari, who was once a childhood friend. "...I've become more mature." Akari was as kind as ever to me, pathetic. "Get out right away!" Despite his raging fury, my brother went on a business trip. I couldn't contain the feelings I had been hiding and pushed Akari down.
