双子の男女がわからない

Takushi Hatsujou fell in love with the sister of a pair of twins during their childhood, and they even promised to marry when they grew up. After a ten-year separation, Takushi finally obtains his grandfather's permission to fulfill that promise and reunites with the twins.

To his shock, both twins now appear as girls. He knows that one of them is cross-dressing, but he cannot tell which is his beloved childhood friend and which is her brother. This confusion turns his long-awaited reunion into a daily puzzle, as he must navigate their interactions and uncover the truth without offending either twin.
