“I’m all you need right, Nii-san?”... more>>
My parents remarried and I got a step-sister two years younger than me.
However, my step-sister became a shut-in after being bullied in middle school.
In order to get my shut-in step-sister to open up to me, I, as her older brother, made a lot of attempts and as a result, I was able to get her to let me into her room.......
“―I, have become unable to live without Nii-san♡”
As a result of comforting and continuing to act as her big brother,
Before I knew it, I found myself facing advances from my affectionate and sometimes aggressive step sister every day.
