^^ I've been watching them on Youtube and Google videos :) if you want to watch the first season first just type in Hana Yori Dango, at first it will come up with an anime but just skip that and soon you'll find the live action. If you want to start with the second season (it's WAY better if you watch first season first.) then type in Hana Yori Dango season 2 on google and it comes up with it.
AHHH 4th episode today! I've been DYING to watch it. Eek what happened to Makino!
