She's outwardly confident, self-centered, cool; however she's very self-conscious and proactively acknowledges her mistakes, saying things like "that's on me" and "that was my bad", becomes apologetic when she feels something is her fault and will go to great lengths to make it up to the affected, and tries to reciprocate kind gestures
She has a cute side that comes out when she's flustered, which happens quite easily, so she's vulnerable to teasing while she scrambles to regain her composure
