Adam's Sweet Agony

The secret of the new student, Itsuki Sonomiya, is that he is the only person in the world who does not suffer from impotence. Protecting this secret in a school with more than 90% girls proves to be challenging. However, following a certain event, Itsuki catches the attention of the school's guide, senior Akari Himeno, who realizes that he is in fact, very special.

Ms. Shiina is one extremely frustrated teacher! Since the pandemic, when all of humanity became impotent, she's been longing for the presence of a man who could satisfy her.

Aki, in a high school surrounded by women, is seen as the "prince" of the school grounds, and looks down upon impotent men. Then, one day, Aki finds Itsuki in the school's unisex locker room, huddled up to hide himself.

Yue, the daughter of a wealthy family, had received an order from her grandfather to find a fiancé. Through a strange twist of fate, Itsuki and Yue find themselves on the ground, with their bodies pressed against each other, and Yue's hand touches Itsuki's bulging crotch.

Itsuki finds himself in an empty classroom, where Yue makes an engagement proposal to him. It's at that moment that Himeno arrives. Sensing the 'romantic' atmosphere between Yue and Itsuki, Akari takes Itsuki alone to the restroom.

Itsuki, who secretly purchased an erotic book at the bookstore, coincidentally runs into Aki as he leaves. It turns out that Aki has also bought an erotic book, and it's at that moment that Itsuki starts to become highly aroused.

The student council heads to the beach in order to plan for the upcoming school trip. There, Aki discovers that Itsuki was lying when he claimed that he couldn't deal with his erections by himself.

Itsuki's secret, that he's the only one in the world who is not impotent, has now been revealed to Akari, Ms. Shiiha, Aki, and Yue. How will the story end as these four Eves compete for Adam?
