...I'm not sure what the relation is, but to those who don't quite understand why Erica seems to be getting hot and bothered:
As NISIOISIN, the author of Bakemonogatari/etc. says in one of his novels, brushing teeth is actually quite a pleasurable experience, and that we don't actually feel it because we're usually doing it ourselves. When someone else does it, it becomes erotic and sensual...or something like that.
Not sure if this is some sort of strange belief in Japan, or that the artist drew this with the above NISIOISIN idea in mind.
I don't know why this is so damn arousing to me, having someone hold anothers face like that makes them seem really small and innocent.
I can brush my teeth by myself.BarkhornThat's no good, Hartmann. You're such a slob that it's obvious you'd never brush your teeth sufficiently!That's not true.Shut up, Hartmann! You never brush all the way in the back properly, do you!Fhaff frot fruu.Ai fam fhrush fii feefh rai raifelf...
