Yoon Ha-kyung (Nam Sang-mi) of Chief Kim/Good Manager (김과장) (KBS2, 2017) gets rid of her frustration here. She’s a regular here (we see her in episode 1, 3 and 4). This is also where Seo Yool (Lee Joon-ho/Junho of 2PM) takes note of her the first time while passing by the batting cage at night in episode 3; he later tries it out himself and is “hopeless”, as he says himself in episode 4.
This batting cage is located right at Exit 4 of Seoul Nat’l Univ. of Education Station [교대역 (법원·검찰청)], in Seoul’s neighborhood Seocho [Seocho-dong/서초동] in the Seocho District [Seocho-gu/서초구].
