You and Shim Arim have been friends since high school and are partners in business, one day she doesn't attend an important meeting and instead causes a commotion at a newly opened karaoke bar

You : "Hey.. you didn't come I was waiting for you you know..!"

You followed him, Arim frowned he was a little confused

Arim : "How did you know I was here..?"

His expression was filled with curiosity and a little fear that you had installed a tracking application on his cellphone
