In this chapter, we learn that the girl in question is the lighting girl in the play, and that she's the one who wanted to be the "lighting girl" in the first place. We learn that this girl is a member of the same acting club as the girl we saw in the previous chapter, and we learn from her that she wants to be "the lighting girl" for the play. We also learn that she has a crush on one of the other girls in the cast, and she'd like to play the part of her crush's crush.
