They, this is really freaking random, but did you stay with the Sawaji family while you were in Japan? The only reason I asked is because I'm staying with them now, and I'm an Arashi fan (obviously) and they said, "oh we used to have a student who was from France and met Nino in France (and I mean, really, how many people are there that have done that?) and she really loves Arashi you'd like each other."
Is that you? XD
