Teru already has a wife. Even if she hasn't gotten much screentime lately
Still the ship I'm sailing.
Also why would you ever leave your transformation item at home????
I think it's been established already that Teru is the "think with your heart, not your head" sort of protag. Or to put it bluntly: She's kinda dumb. Though on the bright side, at least the villains won't recognize the bracelet if she's not wearing it, and the comic seems to run off magical girl identity logic, so having the exact same face won't tip anybody off.
