The lady might dress like a man in the manhwa to challenge societal expectations or to embark on adventures that would otherwise be restricted to men.
It could be that dressing like a man gives her a sense of empowerment or helps her achieve a specific goal. Or perhaps it's a symbolic gesture within the story's themes and motifs.
Maybe it's for some kind of disguise or to protect herself. Could be a plot twist.
Well, it could be part of a plot twist or to show a different side of Thor's character. Maybe it's a way to challenge gender norms in the story's world. It's all up to the author's imagination!
Nezha was dressed like a girl because he used traditional Chinese mythological characters in the animation production, and traditional Chinese mythological characters usually had feminine characteristics. In addition, Nezha is a mythical character. His image and dressing may have different explanations and changes in different cultures and traditions. Therefore, in the animation production, some styles that conform to the aesthetics of modern culture and traditional mythical images were adopted.
I recommend two novels about transmigrating into the elderly to you. The first book was 'Battle Break: I'm Just an Old Man'. It described the story of an old man who had transmigrated to become the oldest old man in the Jia Ma Empire, Wu Tan City, and the Xiao clan. He even faced the Hall of Souls. The second book was " Live the Rest of My Life Well ", which was about a 70-year-old man who realized that his life was not over yet and decided to live every day well. The novel was full of family emotions.
There were a few recommended novels that were about dressing up as an old man. The first book was " Quick Wear: A Guide to Endowment ", written by the Quick Wear Mad Demon. This novel was about a veteran quest taker, Qiao Mu, who was tired of scheming and emotional disputes, so she applied for a retirement quest. The second book was 'I Am Only an Old Man' and described the story of an old man who had transmigrated into the Jia Ma Empire, Wu Tan City, and the Xiao clan's oldest old man. He even faced the Hall of Souls. The third book was " Becoming a Portable Granny ", which told the story of a female protagonist who never thought she would transmigrate to become an old granny. These novels were all about transmigrating into old people, and there were no CP lines.
He might be doing it for fun. Weddings are often full of joy and celebration, and kids like to be part of the merriment in their own creative ways.
One such story could be 'Twelfth Night'. In it, Viola disguises herself as a man named Cesario to enter the service of Duke Orsino.
Sorry, I don't have the specific information. You could try looking at manhwa review websites or asking on manga-related social media groups.
It could be that she has some unresolved feelings about her marriage. Maybe it ended in a way that she didn't expect or want, and being in the dress is her way of dealing with those emotions. For instance, if her marriage ended due to a sudden event like the death of her spouse, wearing the dress and wandering could be a way of keeping his memory alive.
