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 that pretty girl at the train station is wearing. That Milbon scent is lovely! Her glowing skin... must be some kind of treatment! Which brand's cosmetics is that? All of those "cute things" he used to obsess about, now appearing before him in person! (Source: Comic Polaris, translated)
