Korekara Anata o Ubau kara!!! -Yuuwaku ♥ Soudatsu ♥ Sisters-

Ishidou Narumi, a student attending a rural all-boys' school, spends his noisy but enjoyable days with his slightly ditzy best friends.
He has a "secret" that he has not made public.

In this all-male school is a popular, gentle health teacher named Mitama, who seems to be the human embodiment of healing.

Another one is Aya, his homeroom and chemistry teacher, who is feared because of her sharp eyes and strict attitude, but is also popular because of her model-like appearance.

As the only ladies in a school with no female students, these two women and Narumi have a "special" relationship that they do not tell anyone about.

Although they act respectable at the school, it's all just a facade. The truth is that one is a spoiled, no-good Oneesan, and the other is a timid worrywart born with a bad look in her eyes. Since he happened to know those sides of the girls, Narumi has developed a particularly close relationship with them.

However, they were still teachers and student. No matter how close they were, there was a line they would never cross. But the situation changes drastically when an enfant terrible named "Patricia" enters the picture.

Patricia (aka "Patty"), arriving as an English teacher, falls in love at first sight with Narumi after a certain incident. Being a bundle of energy, Patty quickly makes a move on Narumi (in a naughty way)...
From there, his relationship with Mitama and Aya begins to change.

Who will win this sudden battle?

Mitama, the pampered Oneesan?
Aya, with the face of a wolf but the heart of a rabbit?
Or Patty, rushing headlong into everything like a wild boar?

It all depends on Narumi's lower half...?
