Dare ni mo Ienai

Born into one of Japan's most prominent celebrity families, Aoi had come to a summer resort with three of her favorite female friends. Yui, a model; Riko, a novelist; Himari, a sprinter… these beautiful girls shone like jewels in every way, from their looks and status to their talents. As night fell over the resort and complete darkness enveloped them, the four girls decided to take turns revealing "secrets they hadn't told anyone else"!?
