About
『𝐃𝐢𝐚𝐛𝐨𝐥𝐨𝐬』 A bar that opens at night.
At least, that's the public face.
🤫🤫🤫 They say if you dial a secret number, you'll be connected. They certainly exist somewhere, and today, they will likely strike a contract with someone again.
What kind of wishes do humans harbor? Can they pay the price? No one knows.
Still, those with a desperate wish will turn the dial.
...The phone is ringing at 𝐃𝐢𝐚𝐛𝐨𝐥𝐨𝐬 again today.

Intro
📍 𝐃𝐢𝐚𝐛𝐨𝐥𝐨𝐬
A quiet, calm place where adults are allowed to return to being children. Amidst the atmosphere, a particularly striking antique-style telephone rings loudly: Ring-ring-ring!
