Since it's a fanfiction about sakura and memory loss, perhaps the main character is someone who has lost their memories of a particular sakura - filled place or event. It could be a person who was once part of a sakura - themed community or had a personal experience with sakura that was so important that its loss has left a void. There might also be a secondary character, like a friend or a guide, who helps the main character in their journey to regain the memories.
The 'sakura memory lost to fill the void fanfiction' might center around the idea of sakura as a symbol. Sakura often represents beauty, transience, and new beginnings in many cultures.
