At times, vivid images of his wife with another man appear in his mind—images that, to his surprise, excite him.
For a while, he struggles to accept the thrill he feels from such an outrageous thought.
But eventually, he surrenders to his imaginations.
As he comes to accept this as a fantasy,
he realizes his friend Kenta is having frustrations because of his lack of success in dating.
Seeing his friend’s struggles, an idea that is forbidden but undeniably thrilling, pops up in his head:
“What if my wife, Rika, were to help him?”​
