The lies start piling up again, although it's through a comedic context this time. But I'd say that manually ticks down the time bomb timer a little...
Fortunately for them Himari is so much of an airhead they can get away with such flimsy and outlandish lies, for now(?)
If she has an entire flowerbed growing in her head as this seems to suggest, that could be one flaw for her so she's not too perfect as the fan favorite. Just don't tell me Himari actually figured it out a long time ago and is just playing along while still aiming for him. The worst copout would be a reveal that she was playing wingwoman all this time having known they were already married. I feel like riots might start if that happened...
