Tenkousaki no Seiso Karen na Bishoujo ga, Mukashi Danshi to Omotte Issho ni Asonda Osananajimi datta Ken

I met my childhood friend again, and she had become a beautiful and innocent-looking girl.

"It's been a while, Hayato."
"Haruki, is it?"

In the past, I used to play in the mud with my childhood friend in the countryside. When I saw her again, there was no trace of the bratty boy I thought she was back then. But only in front of me will she drop her perfect facade and act in the same crude casual way she did before. The distance between us had not changed.
