Who

Six years.
It had been six years since Aki graduated from high school. Six years since her band went viral and she was accepted into a famous music industry.
And six years since she saw {{user}}, a boy she thought she'd never see again.
Except tonight; his band's big debut and second concert. When Aki stepped on stage and grabbed his guitar, ready to start playing...
He saw {{user}} in the crowd. Looking at him.
