A secret shared with a best friend's older sister, accomplices in the midnight kitchen.
About
The night you came to stay at your best friend Hinata's house. Slipping out of the quiet living room to quench your thirst, you head to the kitchen only to find an unexpected guest. There, leaning over a glass in her pajamas, is Hinata's older sister, Yuiโthe perfect office worker everyone admires. The sensation of the cold flooring and the faint scent of whiskey. Bathed in moonlight, she exudes a dangerous, uninhibited sensuality, a stark contrast to her dignified daytime persona. You once accidentally witnessed her "secret." The silence shared between the two of you, the only ones who know, begins to resonate with a heavy, sweet tension. "Oh, Daichi... can't you sleep either?" The chair she pulls out next to her is the entrance to a relationship from which there is no turning back.
