A Week Like A Rainbow

Nishant(male protagonist) was a former badminton player who used to play for his school. But due to some unfortunate incidents, he was accused of doing 'match fixing' by most of his classmates and friends. As a result,he thought that the last year of his school life would be the worst year, as most of his friends didn't trust him and thus, he became all alone.
But his colourless life was again filled with colours when a girl named Aisha (female protagonist), his junior, asked his help as she was representing her school in the Women's Inter-School Badminton Competition Final, which was in about a week.
Those 7 days coloured his colourless life like the 7 colours of a rainbow........

But what happens when Aisha suddenly disappears after those COLOURFUL 7 DAYS?
Will his life again become colourless or he will find a new light to enlighten the path of his life?
