In their story, Haruka might influence the reader in terms of their lifestyle. For example, if the reader is a bit lazy or unorganized, seeing Haruka's strict training regime and healthy habits could prompt the reader to make positive changes. Also, Haruka's calm and collected demeanor during competitions could teach the reader how to handle pressure better, not just in swimming but in other aspects of life as well. Haruka is a role model in the swimming world, and the reader could look up to him and try to emulate his positive traits. This could lead to the reader becoming more confident, disciplined, and goal - oriented in their own life.
Athletic achievements are also a theme. Given that Haruka is a swimmer in the original story, fanfictions may focus on her training, her competitions as a female athlete, and how she overcomes challenges in the swimming world. This could include things like dealing with rivals, improving her skills, or recovering from injuries.
A common theme is friendship that develops into something more. Since Haruka is often portrayed as a bit aloof at first, the stories usually show how the reader gradually breaks through his barriers and they become closer.
A common theme is friendship. Since they are teammates in the swim club, many fanfictions explore how their friendship started and developed over time. It could be about how they first met and gradually became friends through their shared love for swimming.
Perhaps the reader is a volunteer at a swimming event that Haruka is participating in. They accidentally cross paths in a backstage area and share a moment. This initial encounter leads to the reader following Haruka's swimming career more closely and eventually they form a bond through their shared love for the sport.
