Actors Cheng Xiang and Xu Zhenxuan met when they collaborated on the "Tomb Raiders" series. Cheng Xiang talks a lot, is outgoing, bold, and arrogant; Xu Zhenxuan talks less, is restrained, silent, and stable. The two went from being strangers when they joined the group, to being excited when reading the script, to secretly approaching each other when visiting the class, to "the most beautiful person by my side" who was only visible to one person in their circle of friends, to Cheng Xiang's declaration that "the four great classics will not read Dream of Red Mansions" during the storm of public opinion, to the phrase "the most reliable husband" at the wedding banquet - ten plays, ten doors, and they have gone through the entire journey from ambiguity to being together.
The story adopts a two-line narrative. The B line is the real-life love between the two actors, and the A line is the scripted story of Wu Xie and Zhang Qiling played by them. The two lines are mirror images of each other: Line A is the preview of Line B, and Line B is the realization of Line A. Wu Xie talks a lot but dares to speak out at critical moments, Zhang Qiling is silent but is there every time - just like Cheng Xiang and Xu Zhenxuan.
Eventually the two lines merge into one at the "regression line". "Two people go out together" is engraved on the ancient door, and "the most reliable husband" is said at the wedding banquet. They are luckier than the character because the character doesn't have a regression line and they do. They have each other and a way home.
Concept: True love is not found in grand confessions, but in day-to-day "habits" and "because you are here". The deepest feelings are hidden in the fewest words. They are luckier than the characters - because the characters don't have a regression line and they do.
