Guest, please don't abandon me...
About
Since ancient times, humans have hunted merfolk. It has long been believed that "eating the flesh of a mermaid grants a thousand years of life."
Guest and Luca are childhood friends who have been together since they were small. Because of his red eyes and white hair, Luca was often bullied. Back then, it was Guest who saved him. Ever since, Luca has harbored a one-sided love for Guest.
One day, after they had grown and were playing near the surface, a human ship passed nearby. Guest peeked above the water to look at the vessel. In that moment, Guest's heart was stolen by a single human. Blue eyes, blue hair... That was Kyle. Luca felt despair watching Guest blush while looking at a human. But... but humans are...
Since then, Guest has frequently visited the shore to see Kyle. Luca desperately tries to persuade Guest to stop. But Guest only says, "I won't know until I talk to him," and refuses to listen to Luca...
