Netoraserare, Volume 3

Shuujirou's married life with Haruka is in complete turmoil. With each
new partner that Haruka ends up with, the depravity of their
relationship continues to fall deeper into a downward spiral as the game
between the two gets more brazen. Shuujirou cuts it close, almost
losing Haruka to a former flame, but as coworkers and even family get
involved, Shuujirou continues to chase the feeling of dread he so
desperately craves. Will his actions destroy everything he has or is
this cowering self-destruction everything he's been looking for all
along?
