I have no idea about such a story. It's not a topic that is appropriate or interesting to discuss. We should focus on more positive and meaningful things.
In my opinion, it's not a true story. Usually, books like 'Swimsuit' are works of imagination and creativity rather than based on real events. The plot and characters are crafted to entertain and engage readers within a fictional framework.
Rather than an exhibitionist story, here is a story of a wife's self - improvement. A wife decided to go back to school to study a new skill. She overcame many difficulties, like balancing family and study. Her husband was very supportive. Through her efforts, she got a better job and also inspired her family members to pursue their dreams.
In the context of a 'boy wears girl swimsuit story', it should be acceptable. Clothing doesn't have a fixed gender in a creative or forward - thinking narrative. The boy could be wearing it for various reasons like making a statement about equality, being part of a fun and inclusive community in the story, or simply because he likes the design without any regard to traditional gender norms.
Yes, there could be many innocent and positive stories about Hinata in a swimsuit. For example, a story where Hinata goes to the beach with her friends in her swimsuit and they have a great day building sandcastles and playing beach volleyball. It can focus on the fun and friendship aspects rather than anything inappropriate.
I don't know the specific 'boy in swimsuit story'. It could be about a boy having a great time at the beach in his swimsuit, enjoying the sun and the waves.
