When she graduated from high school, Lin Wan hid her secret love on the back of her graduation photo, thinking she would never see her classmate Lu Shi'an again in this life. Ten years later, she became an ordinary white-collar worker working nine to five, but he appeared in her company's conference room as a representative of Party A. The young boy who once lent her an eraser and gave her lectures is now wearing suits and ties, smiling calmly. Every chance encounter after the reunion was like a drumbeat of fate - he remembered the taste of milk tea she loved to drink, and every letter she wrote that was not sent. This time, she decided not to miss it again. A gentle and slow journey of making amends for regrets begins with calling "same tablemate".
