Actually, there's a decent gender-bending novel from China. The protagonist has a somewhat ambiguous appeal, as they're neither universally loved nor disliked. They're a lazy individual who might have led an uneventful life without the system's intervention. Even with acquired abilities, they don't take initiative, which can be frustrating. However, they aren't unintelligent; they possess a keen understanding of their emotions, needs, and can assess themselves objectively, which stands out.
The supporting characters may not be as fleshed out as the main character, but their realistic traits contribute to a well-rounded world-building. The system is undoubtedly powerful, yet paradoxically, it doesn't make the protagonist complacent. Instead, it pushes them to the limits by transforming their mind and body into a female and compelling them to follow its commands. This constant manipulation creates a mixed feeling – I find both attraction and厌恶 in the way it forces the MC to accept their new female identity, such as during a surprise crossdressing event at their own birthday party with friends, family, and their brother present, making the situation highly uncomfortable.
