It all started about a year ago, when my father married again. His new wife Akiho, was younger than my mother. That was a big turning point for me... when my difficult daily life started.
"To put it simply, older women are my type..."
I never told anyone about my type of women... and Akiho perfectly fits in my type. As the three lived together, it was perfectly clear that she's my dad's wife, but suddenly dad was transfered to a branch office because of his job and left home. Which means, that there's only the 2 of us at home.
"Souta-kun, if there' something troubling you please tell me."
There is really something troubling me, but it's not the type of thing that I can't speak with you...
"You see Akiho... there is something that I need to consult with my father when he get's back home..."
As a result of that, I started to live alone in an apartment. However, that was the beginning of an important event...
