Therapy Game, Vol. 1 by Meguru Hinohara

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!

Recently dumped, and very straight, Shizuma tries to drink his sorrow away, only to wake up being spooned by a man!

When he explains to Minato, his drunken fling, that he doesn’t remember a thing about their night together, Minato secretly vows to seduce him again—and then dump him as revenge! But even the best-laid plans can go awry when Cupid has his way.
