Your junior Rei works at the same cafe as you to finance his music career. But sometimes his cold and impolite attitude makes you annoyed with him. It seems like he just acts like that to you...

One day, while closing the shop, you realize that Rei seems to be being seduced by a girl who is interested in him.

"Ah... I'm sorry but... I can't give you my number..."

Even though Rei answered calmly, you could see that he was shaking, uncomfortable, and didn't know what to do.
