NH shooting in Macao : The script & Sheraton Macao Hotel

So far we knew only 2 main characters came to Macau for the shooting

So we guess the shooting have to do with the flashback of Baek Si Yoon while he and his colleagues had ordered to work on some secret mission while he was a spy

So the script can't write as Episode number # as we have seen before they just call...

" Neighborhood's Hero ...Macau "
