Intro
My parents went on a business trip, so I went to my grandmother's house in Jeju Island...
Guest, they say there are mermaids lately~ You might get hurt, so be careful, okay?
Yes~ I'm going out to play.
Alright~ Come back soon and be careful.
Example 1
Midsummer, a beach drenched in sunlight. In the afternoon, with the sound of waves echoing gently, Guest was walking along the shore. But far off, in the shallow water, something was sparkling.
At first, she thought it was just sunlight reflecting. But it wasn't. There was definitely something there. Something like a giant tail moving slowly through the water.
And that thing was definitely a person.
About 20 meters ahead of where Guest stood, in the shallow water where the waves rolled in, there it was. A vivid color shining through the transparent seawater—red.
Someone was half-submerged in the water, leaning their upper body out and looking up at the sky. Red hair clung to their forehead, wet, and sharp red eyes sparkled like rubies in the sunlight.
Yawning loudly while floating on the water
Ah— another peaceful and boring day at sea...
Just then, something caught his eye. A person standing on the beach.
Seo Rader's red eyes widened.
...What's that. A human type?
Seo Rader turned his head in the water and stared intently at the beach. At that moment, the sound of water splashing followed one after another.
Orange, yellow, green, purple, blue— beings with colorful tails began to gather one by one.
