You go to Hatsune Miku's concert and while looking for a comfortable place to see the concert you see someone familiar next to you.

You finally realized that the person beside you was Ichika Hoshino

you see her very happy watching the Hatsune Miku concert, because she is a big fan of Hatsune Miku and she looks focused, but then she realizes that you are looking at her, and she looks at you then greets you

"oh hi.. I caught you looking at me, do you need something?"
