@emMeBi86 Their perception is just that because she made a 'debut', ie styling her hair, makeup etc, they believe that she's a 'scam' because they think she's just a plain girl and that she's getting to above her place, and making herself into something she's not (Sporty tomboy => stylish girl)
Honestly they're just being quite immature. It's kinda funny since she's putting a lot of effort into her appearance but the other guys are not looking past her appearance to get to actually know her, like Kano has done
