One possible theme is acceptance. Draco would have to accept this new and strange situation that his body is in. It could also be about empathy, as he would gain a new understanding of what women go through.
He might cry a lot. Deku is very emotional, and being cheated on would be a very painful experience for him. He could also get angry, which is rare for him, but this situation would be so unjust that he might not be able to hold it in. He'd probably start to question his self - worth too, thinking that there was something wrong with him that made his partner cheat.
Often, when Deku gets hurt in fanfictions, it forces him to reevaluate his abilities. For example, if he gets injured in a fight he thought he was prepared for, he might start to question his training methods. This self - reflection is a big part of his character development.
It could be a story that challenges gender norms. In fanfiction, the author might be exploring how Draco, a male character, would deal with the physical and emotional aspects of a period if he were to experience it. Maybe it's a magical situation where a spell goes wrong and he gets this unexpected 'condition'.
In fanfiction, if Deku gets kidnapped, his friends from U.A. High would likely launch a rescue mission. Bakugo might be especially determined, as much as he tries to hide his concern. They would use their quirks in creative ways to track Deku down.
There's also 'Injured and Alone'. In this fanfiction, Deku gets hurt while on a solo mission. It delves deep into his thoughts as he tries to survive in a dangerous situation, all while being severely injured. It's a great read for those who like character - centric stories when the character is in a tough spot.
Well, in the fanfiction, Deku might get a new look that changes how others perceive him. Maybe his friends at U.A. High are really surprised by his new haircut and it could lead to some funny or heartwarming interactions.
Well, it's popular because it taps into real - life issues like bullying. Many readers can relate to Deku's experiences on some level. Also, it creates a sense of drama and tension. We as readers are rooting for Deku to come out on top, and the whole process of seeing him deal with the bullies and grow stronger is very engaging. Moreover, it gives fanfiction writers a chance to put their own spin on the character and his backstory, which is always exciting for the fandom.
