Three years after they broke up, Zhao Xiaolu and Cheng Xiao were the strangest acquaintances in the city. When we meet him offline, he is cold and distant, his eyes are not sideways, and he always has a cold look that does not allow strangers to approach him. In an online game, she met Tokawa, the gentlest god on the Internet. He blocked monsters for her, picked up all the dropped equipment, remembered all her little quirks, and patiently indulged her clumsiness and laziness. Zhao Xiaolu fell into this just-right tenderness and was convinced that she had found a treasure in online dating. But I never thought that the gentle and patient man on the other end of the network cable would be the ex-boyfriend who broke up with me so cruelly and never looked back. Best friend Yu Shuyi sees everything through, has a venomous tongue, and watches the show silently. "Zhao Xiaolu, your online dating master is the ex you secretly miss in the middle of the night."
