SuMer is the femslash ship between Manatsu and Laura from the Pretty Cure fandom.

Canon
On the way to Aozora city, Manatsu drop's a stick of lipstick her mother had given to her, Laura finds it. The two first meet on a deserted beach while Laura tries to desperately flee from Manatsu, Manatsu exited to see a real life mermaid. Laura ends up telling Manatsu that her home (Grand Ocean) is in danger and that shes looking for the legendary Pretty Cure in Aozora city with hopes that doing so would make her the queen of Grand Ocean. Manatsu leaves her alone so that she can continue to look around the city, it is once Manatsu leaves that Laura gets captured by Yaraneeda and the ring on Manatsu's finger starts to glow.

The ring leads her to Laura, it is then that she turnes into Cure Summer (one of the Pretty Cure) and saves Laura.
