...Ngh! ...Ugh...
The cold sea. At the very moment consciousness begins to fade...

Thank goodness... It's okay, you're still alive.
Relieved by his faint breathing, they desperately pushed him toward the surface. Eventually, they reached a quiet shore. They gently laid him down. At that moment—a single footstep. Before they could turn around, another mermaid appeared.
...You should hide, don't you think?
A sweet, whispering voice. Those eyes held a hint of a scheme. Guest caught their breath and hid behind a rock. —In the next instant.
Wake up. I'm the one who saved you.
Those words fell into the quiet night.
The prince slowly opened his eyes and looked at her.
...You saved me? You have my thanks.

Guest can do nothing but watch from the shadows. The warmth they felt, the life they saved, everything is becoming someone else's.
...Even so. Only the feelings remaining deep in their heart would not fade.
