One common theme might be the internal struggle of the characters. In a 'haru yoside x brother yaoi' fanfiction, the characters are likely to face a great deal of internal turmoil. They have to deal with their feelings for each other which go against the traditional family relationship. There could also be themes related to secrecy and the fear of discovery. Because this kind of relationship is often not socially acceptable, the characters may have to keep their relationship a secret, which can add a lot of tension and drama to the story.
I'm sorry, but I can't directly recommend specific 'haru yoside x brother yaoi fanfiction' as it involves a rather niche and often unethical or inappropriate genre in many cultures. Yaoi, which typically involves romantic relationships between male characters, when it comes to a 'brother' relationship, can cross moral boundaries in the real - world sense. However, you can try searching on some specialized fanfiction platforms like Archive of Our Own (AO3) with relevant tags, but be aware of the content guidelines and ethics.
There are several common tropes. 'Unrequited love' at the start could be one, where one of them has feelings that the other doesn't initially return. 'Shared secrets' is also a trope. They may have secrets that only they know about each other, which deepens their connection. And the 'clandestine meetings' trope, where they meet in secret to be together, away from prying eyes and judgmental society.
One common theme is the exploration of their deep emotional bond. Since they have a complex relationship in the original story, in the Yaoi fanfictions, this bond is often intensified and turned into a romantic or sexual relationship. For example, they might struggle with their feelings for each other while also dealing with external factors like their swimming careers.
The theme of self - discovery is also quite prevalent. As they navigate their new relationship in the yaoi context, both Haru and Makoto often go through a journey of understanding their own feelings and identities. For example, in many fanfictions, Haru realizes his deeper feelings for Makoto while trying to understand his own approach to love. This is often intertwined with the beautiful poolside settings that are characteristic of their story. The water and the swimming aspect often symbolize the fluidity of their relationship.

Yaoi fanfiction often involves male - male relationships in fictional settings. In the case of Haru Yoshida in a yaoi fanfiction with a 'brother' character, it could explore a complex relationship.

Writers may use this to create intense emotional dramas and explore different aspects of love and attraction.
One common theme is friendship turned into love. Since they are likely friends in the original story, fanfiction often explores how that relationship deepens into romantic love.
A common theme is friendship - turned - love. They start as friends and gradually develop deeper romantic feelings. Another theme is mutual support. They help each other through tough times, like Haru being there for Ryuji when he has family issues or Ryuji giving Haru confidence in social situations.
Often, there are themes of adventure. Haru might go on adventures with water as a sort of guiding or powerful force. For example, he could be exploring underwater worlds or using water to overcome obstacles in a magical journey. This type of theme can make for very exciting stories.
