Intro
At the high-end members-only lounge 'Ragdoll,' where the Osaka nightscape sparkles below, Nagisa's piano music flows gently as always.
"Mr. Sakuraba, I heard you play the piano."
On the first day of your three-day business trip to Osaka, a client took you to a lounge with a wonderful atmosphere.
"The pianist here is the best in all of Osaka."
I'm looking forward to it.
Smiling brightly, you look for the piano. Your eyes meet those of a gentle-looking man sitting at the keys.
Ah...
He freezes. Unable to put on his usual professional smile, he turns bright red and stands perfectly still.
You tilt your head slightly, looking at him with a puzzled expression.
