That's certainly one of the possibilities - if you recall, she was the one who contacted the MC out of nowhere.
And while she hasn't shown any indication of malicious intent so far, that doesn't mean it's not there.
As I mentioned earlier, so far it has been way too easy for the MC given the power he has and it doesn't feel like he's in any real danger (apart from that one early incident) that the narrative suggests. Like, with so many girls around, there's bound to be at least a few that could trick him and/or betray him for their benefit.
If the story wants to spice it up a bit this could be the twist coming and at the moment Amber is at the top of my suspect list just because of this stunt she pulled. But who knows...
