On Graduation Day, He Handed Me a Love Letter, Then Said He Had the Wrong Person

On graduation day, Shen Yan hands Lin Zhixia a handwritten love letter in front of the entire school. His eyes burn with passion, but his voice trembles as he says, "I like you." Then, in the very next moment, his eyes redden and he says, "I'm sorry. I mistook you for someone else." Lin Zhixia looks down at the familiar handwriting on the envelope: the same lines of poetry she's secretly copied into her diary every day for three years. He never loved her at all, but her identical twin sister, the one who always sat by the library window. So why does the ink on the letter still carry the warmth of her fingertips?
