You can try fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms usually have a large collection of fan - made stories about various characters, including Shark Rin and Dolphin Haru.
A plot could revolve around Rin being a bit of an outcast among sharks and Haru being the popular dolphin. They meet and Haru helps Rin to gain confidence and acceptance. Along the way, they develop a deep bond that goes beyond their species differences. It could explore themes of self - discovery and acceptance. For example, Rin could learn to embrace his unique qualities instead of trying to fit in with the other sharks, all thanks to Haru's influence. And as they grow closer, their relationship could be a source of inspiration for others in their underwater community.

One common theme could be care and concern. For example, if Rin is sick, Haru might show his worry in a very characteristic way, like being more protective. Another theme could be vulnerability. When sick, the usually strong - willed characters become more fragile, which can add an interesting dynamic to their relationship.
