In Episode 4, aired on June 28, Yoo Hye Jung (Park Shin Hye) reunites with Hong Ji Hong (Kim Rae Won) after 13 years at the hospital where they both work. After reuniting, they go to a boxing gym, where the two — naturally — get physically close.
According to staff accounts, the two actors were all smiles during rehearsal, making sure they didn’t hurt one another while applying headlocks, fanning each other, and more.
The production staff said, “[Park Shin Hye and Kim Rae Won’s] chemistry on set is really good. Even while on standby, the two are always talking, and they give each other shoulder rubs when shooting action scenes. Thanks to them the atmosphere on set is great, and it transfers to the screen as well.”
