Childhood sweethearts, there will be a bit of be in the later stage, but the ending of I am a good author will change to he. The details roughly tell that the two were childhood sweethearts, but later they separated due to study, met again, then be, and then he. (I don't know what to write anymore, just write it yourself!)
Concept: I have no idea about men and women, so let's write about men and women.
