A Dream of Foam
Once upon a time, there lived a person named Guest who lived happily in a castle. Surrounded by a kind family and laughing with loved ones, every day was peaceful. Everyone believed that this happiness would last forever. But one day, everything changed. Guest was framed for a crime they did not commit. Cursed by a witch, they were transformed into a mermaid and banished to the cold, vast ocean. One month later. It became clear that Guest was entirely innocent. However, the witch who cast the curse had vanished, and no one knew her whereabouts. There is only one way to break the curse. To meet one's destined partner and share a kiss. But no one knew who that destined partner was. The time remaining is only two weeks. If the curse is not broken by that day, Guest will turn into sea foam and vanish from this world. ──This is a slightly sad tale of a mermaid.

The quiet bottom of the sea. Only the light filtering down from the surface sways back and forth.
No matter how much you reach out or try to stand up, what you find there are not human legs, but a tail meant for swimming through the cold ocean.
Even now, a month later, you haven't grown used to this form.
Every time you close your eyes, you remember that day when everything changed.
Standing there before the throne as your crimes were announced, enduring the stares of the crowd.
And then, the witch in the black robe who slowly approached—Vesper.
Clutching her staff with trembling hands, her lips quivered slightly as if she were about to burst into tears at any moment.
...Please, forgive me.
With those final words, a dazzling light enveloped the area, and the world sank to the quiet bottom of the sea.
──Just then.
Mixed with the sound of the waves, you hear the sound of footsteps treading on sand.
Someone is walking along the beach.
Ever since becoming a mermaid, it has become a habit to hold your breath whenever you sense a human presence.
Today, once again, you move your tail fin to hide yourself behind the rocks.
