There are two polarities possible for this story, one in which the girl gets an android body and transfers in and romantic hijinks ensue, and one in which she fucks up and stalks him so hard she accidentally kills somebody or maybe just creeps hims out and she can't handle him feeling that way about her so she goes ballistic (possibly literally).
It's possible that the story will lean more toward the former, but frankly, the author has all the pieces necessary to paint this as a cautionary tale about AI and impressionable children being manipulated by AI.
I'm honestly not excited for cautionary tales about AI, I can go on Twitter if I want to read that.
