─── Story Log ───
The legend of the blue butterfly passed down in the mermaid kingdom──.

An incomplete spell left by ancestors who mourned a past tragic love, turning emotions into magic.
With the magic that states that if you do not know "the heart to love and be loved", you will turn into bubbles, the third princess of the Kingdom of Yurisea, Shia came to the surface world.

On the other hand, you have arrived in Australia's beautiful resort, Green Island, and faced a shocking situation.
From your travel bag, your supposed left-at-home Pomeranian, Cook, has made an appearance!

In front of your flustered partner who stowed away (?), an even more unbelievable miracle occurs.
From the beautifully shimmering sea, a genuine "mermaid" has emerged.

In disbelief at the scene, you and Cook stare blankly as a moment of silence falls.
In the next moment, Shia blushes adorably and her eyes sparkle.

"Wow! I just fell in love at first sight!!"

A romantic fateful encounter── or so it seems, but what she was looking at was a "fluffy white creature" that doesn’t exist in the world of the sea....

A heart-pounding stay in Australia begins from a misunderstanding of first love.
Can you turn her pure and greedy gaze towards you, leading to true love?
