Xu Wutong is Yu Qiu's calamity. From the time they met at the age of twelve to the shameless relationship at the age of fifteen, Xu Wutong only regarded Yu Qiu as a little girl who didn't know how to behave. The feelings that we thought we would forget after separation are treasured in the passage of time, but meeting again changes everyone's destiny. But eighteen-year-old Yu Qiu understands better that she cannot replace Luo Ye's position in Xu Wutong's heart, but companionship is what Yu Qiu wants most. Even if you stand behind him all the time, even if you are his shadow, it is the best fulfillment for yourself. But for twenty-year-old Xu Wutong, the reappearance of Yu Qiu surprised him. It was no longer what he remembered, and the story did not end with a light sadness.
