No, it is not appropriate at all. Forcing someone to wear something against their will, especially in the context of fanfiction which should still uphold basic respect and ethics, is wrong. Yaoi fanfiction should focus on positive relationships and storytelling, not on such inappropriate and non - consensual scenarios.
If you encounter such a situation in yaoi fanfiction, you should report it to the relevant platform or moderator. Most platforms have rules against non - consensual and inappropriate content.
No, it is not ethical at all. Forcing anyone, especially a girl, to wear a diaper against her will is a violation of her basic rights and dignity. It can be considered a form of abuse, whether it is for some malicious prank or improper control.
It's not ethical. Everyone has the right to their own gender identity and expression. Forcing a boy to wear a girl's costume dress violates his autonomy and can be a form of bullying or inappropriate coercion.
There's a chance he could initially feel very resistant and uncomfortable.

One possible reason could be due to a medical condition. Maybe she has some bladder or bowel control issues that the adults around her think are best managed with a diaper for the time being. However, this should still be done with her understanding and cooperation as much as possible.
In some rare cases, it could be due to a misunderstanding or miscommunication. Maybe there was a mix - up in the costume department for an event at school, and he was given the wrong uniform by mistake.
No, it's not acceptable. Forcing a boy to wear girl's clothes against his will violates his personal choice and may cause psychological harm. Everyone should have the right to choose their own clothing style, regardless of gender.
One story could be in a school play where the teacher wrongly assumes a boy should play a female role and forces him to wear a girl's dress against his will. The boy feels embarrassed and out of place.
