Story
Japan in the year 20XX A.D.
A course to study love [Love Communication Studies (a.k.a. “Love Comics Studies")].
In the year 20XX, Japan enacted the “Love Communication Law," which requires all schools to offer a course in love communication.

The story is about a young man who has been living abroad for a long time, but returns to his hometown in Japan after a long absence.
The people he comes to live with in Japan are the older sisters and other family members of his childhood friends in the neighborhood where he played as a child.
These girls had become teachers and senior students at the school, and had grown up beautifully.

Now, Hiroya has spent his time so far at a cutting-edge science and technology research institute in Silicon Valley, USA.
There, Hiroya has been dealing only with super-secret matters and super-high-tech devices before they are released to the world.
He has grown up to be a digital boy who is not good at socializing.

This is why he has no interest in the opposite sex, even though he is a boy of his age.
My sisters are worried.

[If this continues, Hiroya will spend the rest of his life surrounded by machines and die alone!
To prevent that from happening, we have to teach him the right way to love!] [

And so the days of “sister lessons" by the sisters began.
