Ena Asukai

Ena is a gal who is rumored to be a sex expert and to have participated in more than 100 sexual encounters, not as the protagonist but as a lonely and distant student. After Ena passes her exams with good grades, she tells the protagonist that she is going to reward him with sex for helping her. When the two were about to do it, the young man discovers that all the rumors about Ena were false, since she is actually an inexperienced girl just like him.
