I think it's interesting Yuu brought up the paradox of the TS girl before the audience could.
that is, their appeal is fleeting somewhat. Either they eventually adjust and it just becomes a story about a girl or it's forced and insufficiently explores the feminine.
(of course, there are ways around it. One of the best is introducing a second TS girl for them to bounce a dynamic off of or to keep the story concept in the forefront.)
