The male protagonist's old love has returned. Her name is Jane. During a meeting, the male protagonist fell into conflict and pain because of the rekindling of their old love. Here are some of the scenarios I can think of: The male protagonist found that he still loved Jane, but because he had been married for a while, he might not be able to let go of his past feelings. He needed to face his own feelings and think about how to balance his marriage and past feelings. During the meeting with Jane, the male protagonist may recall the past, including the good memories between him and Jane, as well as the difficulties and pains they had faced. These memories may allow the male protagonist to have a deeper understanding of his feelings and may also allow him to understand his relationship with Jane better. The male protagonist may decide to get back together with Jane, but he may also realize that there are already many problems in his marriage, including poor communication, different living habits, and so on. They need to solve these problems again, and at the same time, they have to face other problems in their marriage, such as family pressure, work pressure, and so on. In the process of getting back together with Jane, the male protagonist may find that his feelings for Jane are not as deep as before or the feelings between them have changed. This may lead to misunderstandings and conflicts between them, but they need to understand each other and solve problems together in the end. This was a complicated plot that could involve emotions, marriage, the past, the present, and the future. The readers could understand and interpret the plot according to their own preferences and the direction of the plot.
