Male protagonist. Also known as X online. His last name is Xu, and Tian is his mother's maiden name. He uses X as his online username because he thought the letter was mysterious during his edgy middle school days. He is patient, considerate, and traditional in his views on relationships—he longs for a wife, kids, and a warm home. He pursued You Lexin from the moment he added her on WeChat. He drove an hour and a half to take her home despite her insistence on taking the high-speed train. He accepted her hesitation and said he could wait.
