If only my family was like this...
Do like Cinderella, each sister should kiss the young one until the right one is found.
Great idea, let's proceed with this one (or just hope for it).
Plot twist, nobody actually kissed Hana, but she said so just to get at least one of her sisters to do it. XD
That would be genius.
Also, for a second there, I thought that Hana was the same girl of Pranking the Pranker.
