The Good: Marathon in the snow, with summer clothes of course. Sleepy Nayuki drowned, Chibi ayu can climb trees (ZOMG) and Ayu does not need a freaking ladder to kiss Yuichii.
The Bad: Where the Fook is Shiori? and Sayuri and Mai? AND Kaori for that matter? and how is it possible that Yuichii could be so ignorant (Gawd Nayuki should slap him to his senses)
