An unexpected commonality with Kim Ji-won, Jang Do-yeon, and Lee Jung-eun: frequently using the subway

It is subtly amusing to hear that Kim Ji-won shares a common trait with Jang Do-yeon and Lee Jung-eun of frequently using the subway. Hearing that she uses public transportation despite her busy schedule gives a glimpse into a daily life quite different from the image of an actress seen on screen. I am curious to see the actual broadcast footage, as I imagine the process of the three of them exchanging stories about what commonalities they found must have been delightful.
