I couldn't believe I was being unfaithful... The temptation of playing with fire was irresistible. (Okui Kaede HODV-21832)

Although their relationship was supposed to be limited to physical intimacy, it was just a one-time play with fire, a moment of emotional confusion... The two made three promises: [1] No questioning of each other's lives [2] Only meeting once a month [3] Never taking it seriously. However, from some point on, they both suppressed their feelings of "wanting to see each other," only craving each other's bodies. When they realized they couldn't keep their promises, for the last time... at the moment of their breakup, they indulged in a wildly burning sexual encounter.
