It's been five years since they last saw each other, and now it's time for them to part. They're both freaking out because they can't figure out how they're going to get rid of each other. They both want to have a baby, but they don't know how to do it. The key to the house is lost, and they've been trying to find each other for five years. The only way to get it back is to find the key, and that's exactly what they do. They go around looking for each other's keys, and finally they find the one that they were supposed to have locked up in the house. It turns out that the key was locked in a small courtyard in the city ofjiang nan, where they paid their first deposit. They haven't found each other in five years, so they have to ask each other if they ever regretted the death of their child. The answer is no, they never regretted killing the child. They have to make this man give up on them and their child, because if he knows the identity of the man who killed the child, the consequences of that will be unthinkable. This is the last straw for the two of them, because they have been together for so long. They can do whatever they want with each other now, and the only way they can do that is to make the man give them up on each other
