In a flashback we see how Bong Pil (Kim Jae-Joong) imagined that he had successfully confessed his feelings to Kang Soo-Jin (Uee) at this children’s park on her birthday in episode 1 of Manhole (맨홀-이상한 나라의 필) (KBS2, 2017). But it turned out to be a disaster; the firecrackers went off a second time and Bong-pil was took in by the police before he could confess.
