1st Location: So based on yesterday's info and some additional info I got today, I'll just do a quickie recap of this scene:
Ra Im leaves the car park, turning her back to him and walks away in tears. Joo Won does not try to stop her; just looked on sadly at her parting figure.
The info above is compiled from dc, written by two people who were on-site and saw the whole scene. Please take note that they may have misinterpreted the scene.
Ra Im's neighbourhood at night:
2nd Location: Update on Hospital scene. Someone who saw them filming said Ra Im was wearing the bee hoodie. Thus speculation of her getting hurt at the Stunt Workshop.
3rd Location: Yoon Sang Hyun spotted filming at City Hall, Seoul.
Note: I did not to the heart shape thingy. It was already there.
