it's been 5 years since this relationship started. i made a certain mistake with kitayama-kun, my son's friend, 5 years ago. when my husband's affair was discovered and i was exhausted... kitayama-kun gently supported me and confessed his feelings. touched by kitayama-kun's kindness and feelings, i took his first time that night and crossed the line of infidelity. from that day on, the days of secretly meeting with kitayama-kun, avoiding the eyes of my family, were very happy times. however, 5 years have passed, and the friends-with-benefits relationship, which has also changed, has come to an end...
