In the crowd of people that looked uncountable, a man was smiling while looking at Aiden performing on the stage. At that moment, he was glad that he had decided to attend the concert.
The man was a high school teacher that barely got time outside the working hours. So, when he saw tickets for Aiden's concert, he immediately bought them.
Actually, it was an interesting story as to how he had discovered Aiden.
It was because of a friend of his.
One day, his friend asked him if he could stay at his house for a few days. Apparently, he had been kicked out of his apartment by the landlord as he wasn't able to pay rent and had nowhere to go.
The man had let him stay at his place, and during that time, he used to play 'Revolution', the song that Aiden had composed for the anime [Attack on Freedom].
