There's a fanfic called 'Melodies of the Heart'. In it, Sakura's humming serves as a form of self - comfort while she's on missions away from Sasuke. As the story progresses, Sasuke realizes how much he misses her humming when she's not around. It's a really sweet and emotional story. There are also some fanfics that explore how Sakura's humming can be a source of healing for Sasuke, especially when he's dealing with his past traumas.
I'm not sure of a specific fanfic title that exactly matches, but you could try searching on fanfic platforms like Archive of Our Own or FanFiction.net. Look for tags related to Sakura, Sasuke, and 'humming'. You might find some hidden gems there. Also, some fanfic communities on social media might be able to recommend some good ones. For example, Naruto fanfic groups on Reddit or Facebook could be a good place to start.
In a Sasuke - centered fanfic, Sakura humming to herself could signify her longing for Sasuke. It could be a way for her to express her emotions that she can't put into words. Maybe she hums the tunes that remind her of the time they spent together.
In the fanfic, Sakura might be talking to herself about Sasuke because she's facing a difficult decision that involves him. For example, if there's a new threat in the ninja world and she has to decide whether to send Sasuke into danger or keep him safe. She could be weighing the pros and cons while muttering to herself, thinking about Sasuke's skills but also his well - being. And her feelings for him are also clouding her judgment, so she's trying to clear her head by talking it out to herself.
There might be some extremely niche and dark fanfics that involve such a plot, but it's not something that is mainstream or widely promoted. Most fanfics in the Naruto fandom tend to focus on more positive relationships, character development, or alternative storylines that don't involve such tragic and self - harm - related concepts. If it does exist, it would likely be in some less - known or more edgy fanfic communities.
I really hope there isn't such a disturbing fanfic. Self - mutilation is a very serious and dark topic, and it doesn't align with the positive aspects of the Naruto series. Most fanfics focus on more positive relationships and storylines between the characters.
There are quite a few fanfics out there. One I remember has Sakura's growth as a ninja intertwined with her feelings for Sasuke. It shows how her experiences, like dealing with the fall of Sakura leaves in the village, symbolize her changing relationship with Sasuke. Another one focuses on Sasuke's return to the village and how Sakura, with the reminder of the sakura leaves (a symbol of new beginnings in their village), tries to reconnect with him on a deeper level.
One possible fanfic could be 'Sakura's Secret Dance'. In this story, Sakura becomes a private dancer by accident. Sasuke is initially shocked but then becomes intrigued. It's a story full of emotional twists as they navigate their relationship in this new context.
The plot might involve Sakura having a dream about Sasuke leaving her again. When she wakes up, she starts talking to herself. She's trying to convince herself that Sasuke has changed and that he truly loves her now. She might be going through all the events that led to their current relationship and how they overcame their differences. She could also be thinking about how to make their relationship stronger in the future through her self - talk.
Another idea for this fanfic could be that Sakura has lost her mind because of her unrequited love for Sasuke. She might be talking to herself about all the times she tried to get his attention but failed. She could be in her room, surrounded by memories of Sasuke, and saying things like 'Why don't you see me, Sasuke? I'm right here.'
One great fanfic could be 'A New Beginning for the Uchiha'. It beautifully portrays Sasuke and Sakura's journey into parenthood with Sarada. It shows how they adjust to the new life and the challenges they face as a family.
There's also 'The Protector Sasuke'. This fanfic explores the idea of Sasuke's protection not just in physical battles but also in emotional ways. He defends Sakura from the cruel words of some of the villagers and helps her build her confidence. It's a more character - driven story that shows a different side of their relationship.
