Add more backstory to Sakura. Maybe share her hopes and fears about motherhood before her death. This would make her death more poignant. Also, describe the setting in great detail. A beautiful, peaceful setting during a tragic event can enhance the contrast and thus the impact.
To make it more impactful, focus on the emotions of the characters. Really dig deep into the grief of the loved ones left behind. For example, show the father's heartbreak in vivid detail.
Add some mystery elements. For example, the reason why the character is giving birth alone can be a mystery that unfolds throughout the story. It can keep the readers hooked.
The theme of loss can be shown through the reactions of the other characters. For example, her partner might be inconsolable, feeling a deep sense of emptiness. There could be scenes of him just sitting in the nursery they had prepared, surrounded by the unopened baby gifts, lost in his grief.
One common theme could be sacrifice. Sakura's death during childbirth can symbolize the ultimate sacrifice a mother makes. Another theme might be the impact on the other characters. For example, it could show how the father copes with the loss and the responsibility of raising the child alone. Also, it might explore themes of grief and how the community around them reacts to such a tragic event.
One possible plot could be that the story focuses on the emotional turmoil of those around Sakura. Her friends and family might be in shock and disbelief as they were expecting a joyous birth but instead are faced with her death. They could struggle with guilt, thinking if there was something they could have done to prevent it.
By creating a sense of surprise. If the ending goes against the readers' expectations, it can be very impactful. For example, if a story has been leading the reader to believe that the villain will be defeated in a certain way, but then the hero actually teams up with the villain to defeat a greater evil.
To make it more impactful, you can use vivid descriptions. Describe the scenes of abuse and Ron's reactions very clearly. Also, tie the story into the larger Harry Potter universe. Maybe show how the abuse affects Ron's role in the fight against Voldemort or his standing in the wizarding community. And don't forget to give Ron a strong arc of growth and recovery, which will engage the readers more.
By focusing on the details of Harry's emotions. Really dig deep into his feelings of hopelessness, despair, and self - loathing. Make the readers feel what he's going through.
One possible scenario in such a fanfiction could be that Sakura discovers she's pregnant during a time of relative peace in the village. Naruto is initially overjoyed but then realizes the responsibilities that come with having a child. They both might have to make adjustments to their ninja duties. Sakura's medical knowledge would surely play a big role in her own pregnancy care, and Naruto could be learning all about being a father from his own experiences growing up without his parents.
Well, in fanfiction, it could be that Naruto and Sakura end up together and have a child. The story could focus on the anticipation and excitement of the impending birth. It might show Sakura preparing a nursery with all her love, while Naruto is out on a final mission before the baby arrives.
Use vivid descriptions. For example, instead of just saying 'There was a sad emoji', say 'The sad emoji, with its big, glistening teardrop, seemed to be drowning in a pool of melancholy.' This makes the reader really visualize the sadness.
