A story I heard was about a fairy who lost her powers. As a result, she de aged into a baby girl. A kind-hearted human found her in the forest and took her in. It was interesting because it showed how the human had to adapt to taking care of a magical being in baby form.
One such story could be about a magical spell gone wrong. A young witch was trying to reverse time on a flower but accidentally cast it on herself. Suddenly, she de aged into a baby girl. Her friends, not knowing what to do at first, had to quickly figure out how to reverse the spell. They searched through old magic books and finally found a counter - spell.
One de - aged gay story could be about a man who, through some magical or scientific event, is transformed back to his younger self. He then has to re - experience his journey of self - discovery regarding his sexuality all over again. For example, he might go back to his high school days when he was just starting to realize his feelings for other boys but was too afraid to show it. This time, with the knowledge and confidence of his older self, he might be more bold in expressing himself.
