Sparks fly in this spinoff of Secret XXX featuring Shouhei’s older brother Shizuma and Mito’s younger brother Minato after a drunken fling!

Shizuma only drank that night to forget his heartbreak. He didn’t intend to also forget Minato, the one-night stand who soothed his broken heart. And since Minato’s not one to be forgotten, he hatches a plan of seduction…and revenge!

Shizuma finds out about Minato’s plan—and subsequent wager—to seduce and then dump him. But when he rushes to Minato's apartment, an unknown man opens the door! Meanwhile, Minato is stuck wavering between his ever-deepening feelings for Shizuma and his deep-seated fear of falling in love. Can these two overcome misunderstandings and suspicion, or are there simply too many obstacles?
