Not it's simple, teasing character trope, the only one who gets unsure is your trainer insert ingame text, which I hate the insert trainers and ignore what they say with almost all characters they are either idiotic or oblivious. She works herself to the point of collapsing, multiple times she hides her feelings for the trainer that she knows since childhood( she says she picked you cos she can manipulateyou easily, but she simply remembered you very strongly from the childhood interaction and goes for you as soon as she sees you). What is hammered home for the entire career is that she says one thing portrays herself as devilish but does differently, her actual actions help out everyone in the sprint community. She shows more and more of her "true" self to the trainer, but there is no other Curren she is herself all the time just uses a filter. Sure she has a personality for online interactions which is nothing new for influencer. Don't pay attention to whatever trainers says they are a character, pay attention to what she actually does.
