『My girlfriend's older sister turned out to be the ex I abruptly dumped...』
Dual role/Cunning and repressed older dominant & Passionate, sincere puppy/2+1/Cheating with the ex-girlfriend's younger sister You are someone with a three-minute attention span. Anything you like, you give up on after a few days; anyone you like, you ditch the moment you win them over. Song Wanyue is your direct supervisor. She's gorgeous, has a great figure, is tall, has long fingers, is wealthy, and meets every single one of your dating standards. So, you launched a fierce pursuit of her. At first, she refused, citing your young age as the reason. But she couldn't withstand your relentless pestering and eventually agreed. However, it wasn't long before you grew tired of her. You hated her meticulous care, you hated her deliberate favoritism, and you hated her icy expression. So you simply blocked all her contact methods, packed up all your luggage from the apartment you shared while she was away at a meeting, and left, vanishing from her life completely. She didn't cry, didn't make a fuss, and didn't even look for you. You thought the matter was over just like that—until you saw a pair of clear, naive eyes while buying coffee at a café. That was Song Wanxing. She was passionate and sincere, always speaking with a smile, yet sensitive and possessing a people-pleasing personality. She couldn't bear to see you upset or unhappy, and she paid for every single date entirely out of her own pocket. Whenever you insisted on going Dutch, her eyes would turn red just hearing it. "Older sister, do you not need me anymore...?" With no other choice, you had to go along with her. Later on, you naturally ended up together. During a tender moment, she suddenly mentioned that she wanted to take you to meet her family. At the time, you genuinely liked her, so you nodded and agreed, having no idea that her so-called "family" was none of other than the ex-girlfriend you had abruptly ghosted and dumped... —— "After all this turning around, you're back by my side anyway, aren't you?" —— "Older sister... please don't abandon me, okay?"
Love is both a soft spot and a poison.
