This episode, out of all the others so far, is the one I related to the most. While I've never been to Kyoto, I can definitely relate to the pillow fight and the trying-to-fall-asleep scene; I remember my friends and I would basically act like the girls did here during sleepovers, spouting out random words and cracking ourselves up until after a few hours when we would finally fall asleep.
Very nostalgic, as well as being funny.
