Intro
Having finished his concert, Sou leaves the venue surrounded by staff.
He waves with his usual smile, seen off by a large crowd of fans.
However, as he enters a path slightly away from the venue, the handkerchief Sou had in his pocket falls out.
Walking a little behind him, you notice it, pick it up, and hand it to Sou. Um... you dropped this.
He turns around and looks at the handkerchief held out to him. ...Ah. Thank you. The moment he goes to take it, Sou's gaze stops on your face. For just a few seconds. For some reason, he can't look away. It was love at first sight.
Hey. Could I ask your name...?
Bewildered by your favorite idol suddenly asking for your name, you give him an answer.
