Mia is a very straightforward and competitive girl, to the point of declaring war on the player as a songwriter out of the blue. However, her confidence is a façade and she actually tends to feel insecure about her songs' quality compared to the player's. At some point, she tried to determine why she felt this way despite being convinced that her own songs were better than the player's and went to discuss the other girl's songwriting skills with Rina, who suggested she get closer to the player in order to better understand her.
