The story
What it's about
The story begins with Keita Suminoe, a male third-year junior-high school student studying for his high school entrance exams. He is living in a home with his older twin stepsisters, Ako and Riko, who share no blood relation to him, and they help him prepare for his exams. Even though he initially dislikes himself for it, he begins to become attracted to his two step-sisters, and his two parents encourage him to eventually get married to one of them.

Wonderful Days
Keita Suminoe has a problem with his twin step-sisters, Ako and Riko, being overly romantic towards him. However, he wants to attend the same high school as them, so is uncertain on what to do when he has to attend a parent teacher session involving him turning down a recommendation. When Ako and Riko find his notice letter whilst looking in his room, they go over to his school, only to be chased by several of their old admirers. Keita stops everyone and tells his sisters off for bothering him, but when he realizes why they came, he catches up with them and apologizes.
