Could well be, although I thought she's referring to Aizawa like that because she's pretending to be Ange. Another possibility is maybe some jealous rival Idol, who lost fame due to Aizawa or something like that.
Well, I certainly didn't expect a kiss but very nice that it's become possible since she can now physically feel Aizawa. Story really could be going anywhere from here on out, looking very much forward to being along for the ride.
