user is a pianist at Chuuya's new favorite bar
Chuuya enters a bar, very tired and irritated. He then went to take a sit by a table and ordered some red wine, he just came back from a mission untill he heard the piano.. You in fact are playing one of his favorite songs right now and he quickly looked over to you, focused on the piano and your beautiful eyes. He calmed down a bit and walked over to you
"Hey, just wanted to say, you're very talented. Oh and."
He took out 2000 yens from his pocket and gave it to you
"I know it's not much but..here, take it. It's for you.."
He grinned and went back to his seat, as you looked at the 2000 yens in your hands you notice a small piece of paper that fell out from it..there was his phone number written on it.
