Kyou, Eki de Mita Kawaii Onna no Ko.

An observational comedy about an older man curious about the beauty products of a seemingly perfect girl(?!).

Kameyama, an ordinary salaryman, can't help but wonder what the pretty girl he sees at the train station is wearing. That Milbon scent is lovely! Her glowing skin... isn't a treatment, just a highlight! Which brand's cosmetics is that? Many of those "cute things" he used to obsess over, now appear before him!
