Ah yes, the classic 女体化/性転換 formula of "I had turned into a girl, stayed at my best friend house, and got together as the consequence of my sense of distance remaining the same as before". It's the tried and tested formula, and the most common pattern in web novels of said genre, published on platforms like syosetu, yet somehow it's a pretty rare pattern in doujin works. I concur that it is within a reasonable argument to derive a heuristic postulate that a cliche can be paradoxically formed by trying to avoid the status quo cliche.
