Hospital.
Wu Xue's Room
The married couple in the paper, Wu Xue and Wan Lengya had decided to divorce.
This is the result they've made together. Like how the original Wu Xue waited for 3 years after their arranged marriage, for Wan Lengya to give him his answer to his question a long time ago, now the conclusion is made.
Though there are no divorce papers given to him, their marriage still ended. As Wan Lengya had chosen is Muse, Xing Ran, instead of his wife, Wu Xue, like in the original plot.
Once they'd finished their conversation, the two who were asked to leave the room for a moment were called back inside. Yue Wuya presented the snack Wu Xue requested to him. Macaroons.
