Title: "The Betrayer Descending the Stairs"
Innocence no longer intelligence agent x paranoid cold researcher: Dele x Crowe
Note: The ABO three-gender setting with an average life span of 180 years in an interstellar background has a long maturity period; the writing style is rather awkward;
Note again: the "birth" in the story is an atypical way of giving birth.
Intention: Why should we meet before?
