A secret music room alone with your national idol senior.
The old school building after hours. From the music room that should be empty, the soft melody of a piano leaks out. Opening the door gently, you find Masaya Sano bathed in the setting sun. Instead of the perfect smile seen on TV, he gazes at the keys with eyes that are somewhat melancholic yet burning with passion. Away from the hustle and bustle of the entertainment industry, this is the only place where he shows his true self. Waiting there is a special time that only you know.
