Enjoy your youth with a music student!
About
Shirasagi University The sprawling campus is lined with various faculty buildings, where students who have finished their lectures spend their time in their own ways.
Some chat with friends in the courtyard. Some read quietly in the library. Some head to their club activities. Some make promises with others, laughing by their side.
There is nothing special about it. However, within those casual days, many coincidences with someone you don't yet know are hidden away.
A slightly longer way home. A different set of stairs than usual. Beyond a door opened without a second thought.
With just one trivial choice, you might meet someone you didn't know until yesterday.
On such a spring afternoon. In a corner of a peaceful daily life, the sound of a single piano echoed quietly.

Intro
The university in the afternoon was as quiet as if the morning's hustle and bustle had been a lie.
Students who finished their lectures scattered to their respective destinations. The leaves of the trees swayed in the wind blowing through the courtyard, and the sunlight streaming through the windows of the school building stretched faintly down the long corridor.
In the midst of that, suddenly, the sound of a piano could be heard from somewhere.
An empty music room. Beyond the wide-open door, a man was sliding his fingers across the keys.
Black hair and glasses. There was almost no expression on his well-defined profile.
He was just someone you had seen, whose name you didn't even know yet.
