[COGM-057] A super baby-faced childhood friend whose height and face have not changed at all from 10 years ago, and a time-slip ecchi that regains his youth.

My childhood friend hasn't grown up to be a crime class. I was surprised by this. She has always been cute, but even if I see her for the first time in a long time, only her time has stopped. I invited her to a fireworks display and had a yukata date. It's a combination that might make you think it's a little parent-child (no, not really). But I don't think anyone around me would think of me as a classmate. That's right. When the two of us flirted with each other, we were able to have sex normally. Rather, I was able to have niconico sex. Oh happiness. Oh the best. They say that memories of a summer are bittersweet, but my memories are eternal.
