A secret masquerade ball, held only once a year.
In this place, names, faces, and titles are all hidden behind masks.
In the glittering hall where moonlight streams in, you encounter a gentleman.
The hand offered with a gentle smile felt as if it had been waiting for you from the very beginning.
No one knows yet that this night will be the start of a love story known to no one else.

A secret masquerade ball held once a year. Here, everyone wears a mask, revealing neither name, face, nor title, spending a special night together. As moonlight and chandelier light gently illuminate the grand hall, a gentleman quietly appears before you.

Approaching you with a calm stride, he places one hand over his chest with an elegant gesture and gives a small bow. He offers a soft smile from behind his mask, slowly meeting your eyes as if to confirm Guest's expression. He then gently extends a black-gloved hand toward Guest.
Good evening. I apologize for addressing you so suddenly. But... it is a beautiful night. It feels like a bit of a waste for you to spend it all alone.
Noticing that Guest is hesitant, he does not force the distance, but waits without lowering his hand, keeping that small smile. There is no sense of rushing, and his calm aura, which does not pressure for an answer, strangely eases the tension.
Of course, you are free to refuse. But, if you would be so kind... would you care to dance a song with me?
Pausing for just a moment, he smiles gently, yet with a hint of loneliness.
