BL Game no Shujinkou ni Nattara Rival ni Dekiai Sareta Ken

Kuudere, Devil, Yandere or the Ideal Man - who the hell am I supposed to choose?! Together with his long-lasting rival Wataru, the university student Tatsuya ends up in an unknown world. To his surprise, it was the world of a school BL game! The only way to return to his original world is for the protagonist, Tatsuya, to get the happy ending (= have sex) with one of the in-game bachelors! One time, Tatsuya hears a moaning voice coming from the room next door and accidentally gets an erection. After Wataru sees this, he reaches for Tatsuya...?! Childhood friends and rivals. The devilish student council president, Ujou. The pampered yandere, Ushitora. And the new and handsome transfer student, Kaito. So many different types! But who will Tatsuya choose?!
