mio adachi and i were supposed to be a couple that everyone envied. one day, i finished work early and returned home feeling a little lucky, but there were men's shoes i didn't recognize at the entrance. while feeling a bad premonition, i peeked into the living room and there was my beloved wife with a bewitching expression i had never seen before, devouring my neighbor's dick... i wanted to look away, but my feet wouldn't move as if glued to the floor, and anger, the shock of betrayal, and an inexplicable turmoil swirled in the depths of my chest. furthermore, in my wife's smartphone, there was a video of mio offering her body at the beck and call of her neighbor. realizing that i couldn't take my eyes off my wife's figure on the screen, i decided to lie and say "i'll be late today because of overtime" and investigate the situation while mixing self-loathing and excitement──.
