Giri no Imouto to Kekkon Shimasu

My father remarried. I finally had a new little sister-in-law, and I fell in love with her at first sight.

This is what I, Takuro Matsubara, said at our first meeting.

I will look at her – Toko Konoe – with a sexual gaze.

But for some reason, the sister-in-law’s first impression seemed to be the worst, and our life together began with an ∞ rating.

Besides, I’m a little shy…

What does “a little” mean about me?

“You push me down, touch my breasts and look at my underwear every day!

“I’m sorry, little sister. I didn’t do it on purpose.”

Now that we’ve made a contract, I need some time to get to know the real me…

The hero got pushed by the heroine, and the heroine blushed all over the place!

A 100% brother-sister love comedy with a smile that won’t stop smiling!
