NTR彼女～カノジョを好きなのは僕だけのはず～

"This will be the summer I get together with Wakana!"

Haruta finally decided the day before the start of summer break.
This will be the year he confesses his love. It's been too long.
Wakana surely feels the same, and it seems the summer will be a fun, and fulfilling one.
But...

"Hey, you know that Wakana Nonomiya?"
"Wow, look at the tits on her!"
"Alright, I've decided. I'm making her my sex friend before summer ends."

It seems another boy is after Wakana too under Haruta's nose...
A handsome playboy that's popular with all the girls.

Can Haruta win out against this competition, or will Wakana be used and corrupted?
