Closest would be when she talked that her admiration and feelings for Ame "weren't even as a ship or anything" in the Dokomi panel... but she didn't mean it WASN'T a ship, just that it wasn't only a ship, because she spent the rest of the panel with a blush face on and thirsting for while declaring her love for ame every 30 seconds.
