That Time I Became a BL Game Protagonist and My Rival Doted on Me

"We're now in a world... where it's acceptable for dudes to fool around together, right?" A certain occurrence brings a college student Tatsuya to wander into a parallel universe along with his rival and inseparable (want it or not) friend Wataru. What a place! It was a world mirroring an academy-setting of a BL game! In order to return to his home world, the protagonist, Tatsuya, needs to land a happy ending with one of the main characters(sex!?). But to top it all off, Wataru is also thrown into the mix! Hearing moaning from the adjacent room at the dorm, Wataru catches Tatsuya in quite the arousing predicament. "They say it feels good if you rub them together," Wataru says, reaching out a hand. Stroking in unison, Tatsuya is faced with immense pleasure for the first time! Furthermore, other main characters approach Wataru one after another. Who will join him in his happy ending...? And, will he ever find his way back home!?
