This is a Free! Iwatobi Swim Club/Eternal Summer fanfic that was originally my friend Katiekitty99's but since she lost all inspiration for it she let me adopt it Because I kept having more ideas for it. I hope That y'all like our collaboration. This is about our favorite swimming boys but add in Haruka's twin sister, Kohaku "Haku" Nanase who has a crush on our favorite shark, Rin Matsuoka, and a sweet southern girl from Louisiana named Erica Levesque who has a crush on our favorite dolphin, Haruka. Things get interesting especially since Haku and Erica have been best friends since childhood. What will happen? Find out in this story.
