[IDEAPOCKET x S1] [Nishinomiya Yume x Miru] - A miraculous, one-night collaboration between two of the AV industry's most exclusive actresses, signed to a leading solo manufacturer - I have two childhood friends. Yume is glamorous and moody. Miru is thoughtful and kind. I met the two of them again at a class reunion, and when we got drunk and sneaked into the school at night, we discovered graffiti they had written in their student days. The classroom remains the same, and our relationship has changed. The feelings I couldn't express that day remained silent. "Let's break down together?" The two, who have always loved me, even though I'm now married, develop into a one-night stand, as if to settle their past feelings for me, and to confront each other with their unchanging feelings... In the school building at night, where time has only moved on, a forbidden love triangle begins between the two girls, who have gone from being pretty girls to beautiful women.
