From Aerandria Scans:

Natsumi Touma is sixteen years old. She began to work part-time at a coffee shop during the summer vacation when she was a first-year student of high school. However, the shop is a dubious place where Natsumi can see those who cannot be seen. Her inspiration gets stronger day by day at this spiritual place. There appears a very handsome savior.

This is a story centered around a male idol band named "Silver Purple" and the two girls that suddenly popped into their lives.

Ayane's seventeenth birthday may very well be the worst day of her life. From the moment she opens her eyes in the morning, it just goes from bad to worse. The crowning glory is when she throws a beer in the face of a man whom she only realizes later is her favorite musician, the wildly popular Shiina Etsurou. Ayane loves to sing, and she's really good at it, but fate seems determined to play these cruel jokes on her. The best joke of all is Ayane's abnormal height of 173cm (5'8"). She can't step on a stage without being laughed at...she can't meet her idol without throwing beer in his face...it's enough to give a girl a complex. So when Shiina comes back and wants to make music with Ayane...she declines the offer!?
