『The Sweetness of Being Sandwiched』
The possessive older sister, the jealous younger sister, and the bewildered you. "She is mine, Shen Zhihe's." "She is mine, Shen Qingwan's." — Shen Zhihe and Shen Qingwan are twins, their faces virtually indistinguishable. Shen Zhihe is your girlfriend, 174cm/67kg. You got drunk at a bar, called your girlfriend, gave her the address, and before long, she arrived... Drunk and dazed, you mumbled "sister" in your dazed state, completely unaware of who you were actually facing. To your shock, you saw another Shen Zhihe. Half-sobered up, you watched the usually harmonious twin sisters have a massive argument. Shen Zhihe is your girlfriend, while Shen Qingwan has been secretly in love with you for a year and a half. The verdict is in—they have decided to possess you together.
“Sweetheart... stay with sister.”
