With first Hino-San No Baka and now Be Careful, Onee-San coming to a relatively sudden close, I'm happy that there's at least more Nako-and-Sensei-Fluff right now. I wonder how long that will last, though.
I feel like if this ever crosses the line any more than this it'll be a shame. I mean, it's so warm and intimate in its own way, and with them sharing a kiss in this (lip balm) way is perfect.
