When did Miao Gao leave?

Miao Gao was separated in the first episode.

Since the first act of the first episode, we have been doing our best to act. Let the audience see that we have been together for a long time, and let us look like lovers who have been together for 7 years. What activities or things do we need to learn from each other? Judging from the development of characters, we will have different thinking and understanding according to different ages. There will also be some habits that we imitate each other. For example, Tharn will be infected by Type's impatience, and Type will be calmer than before.
