The MCs asked them, "You guys could like the same the guy, right?" The girls replied, "We settle it right away. We agreed that if the guy doesn't choose one of us, that person would give up without a fuss."
They were then asked if they ever confessed their feelings at the same time. The girls said, "We never did that, but we also settle it before we confess."
They also revealed that as their voices were similar, they even picked up the phone for each other when a boyfriend called.
