This is where Kim Mi-so (Park Min-young) and her sisters come to commemorate their mother’s birthday every year, and where Lee Young-joon (Park Seo-joon) came to visit in episode 10 of Why Secretary Kim/What’s Wrong With Secretary Kim (김비서가 왜 그럴까) (tvN, 2018).
Haesonggwa Bada Pension [해송과바다], or loosely translated as ‘Pine and Sea’, is a holiday pension house located in the village of Uihang-ri [의항리] in Taean County’s [Taean-gun/태안군] Sowon Township [Sowon-myeon/소원면] [Taean-gun/태안군] of South Chungcheong Province [Chungcheongnam-do/충청남도]; around 4.5 hrs south of Seoul by public transport.
While the pensions next door (823/825) may have been briefly featured in the initial scenes of this episode, it is not the pension that features most — which is Pine and Sea at 827.
