I had been drowning in a secret adulterous relationship with my son's friend, Kitayama-kun. Before I knew it, five years had passed. Back then, after my husband's infidelity was exposed, both my heart and body were shattered. He was the only one who gently stayed by my side and filled my loneliness. "You want to get back at him for his infidelity, right." "Isn't it okay if it's me?" He pressed in with a serious gaze. Despite feeling guilty, I was driven to cross the line that night. Since then, we've had many secret meetings after sneaking away from my husband and son. However, upon hearing the news that Kitayama had a new girlfriend, the twisted and beloved relationship that had been maintained for five years began to quietly unravel.
