"We are a sad, divided nation and when it comes to solving this problem, there is no South or North Korea", said Jo Jung-rae, one of South Korea's most well-known novelists, in an interview last week.
Dark chocolate tempered in the shape of barbed wire lay over a map of the Korean peninsula rendered in thin blue chocolate, a representation of the heavily militarized border that separates Games host South Korea and its old enemy in the North.
Even Japanese Prime Minister Shinzo Abe, who has shared the American skepticism of warming North-South relations and pressed Moon against falling for the North's "smile diplomacy", greeted Kim Yong Nam.
Some local media have gone as far as to describe the meeting as "effectively an inter-Korean summit".
The Korean athletes, as they did in 2000, 2004 and 2006, walked into the stadium as a unified team.
North Korean Jong Su Hyon had one of Korea's three shots in the opening period. They appeared in the VIP box at the Olympic Opening Ceremonies on Friday night. It has dispatched a delegation of almost 500 people - mostly musicians, dancers, and an all-female cheering squad - and has been pushing its participation as a sign of willingness to work with Seoul, through greater exchanges, to ease what has been a year of very high tensions on the peninsula.
On one side of the arena, about 75 North Korean cheerleaders dressed in matching red with white caps made noise from the opening faceoff.
Moon and Kim Yong Nam planned to return to the Games venue to watch the joint Korean women's ice hockey team - the first ever combined team at the Olympics - take on Switzerland, the Blue House said. The unified Korean team also marched together in a handsome display under a unification flag but the show stealer was Pita Taufatofua-who competed in taekwondo in Rio's Summer Games and is in Pyeongchang to compete in cross-country skiing-for reprising his bare-chested appearance as flag bearer for Tonga.
Despite the appearance of hacking, the PyeongChang Organizing Committee for the 2018 Olympic & Paralympic Games (POCOG) had yet to confirm whether that was, in fact, the cause of those aforementioned complications.
Pence, who is leading the USA delegation to the Olympics, briefly encountered Kim Yong-nam at the Games but the two tried to avoid directly facing each other.
Moon's spokesman Kim Eui-kyeom said Saturday Kim's sister verbally delivered his offer in a lunch meeting with Moon at Seoul's presidential palace.
"South Korea has some hard homework to solve regarding some countries", Moon told the gathering of some 200 VIPs at the reception before Pence arrived.
A senior administration official aboard Pence's airplane also told reporters that South Korea and Japan "are solidly with our alliance and the need to continue and intensify economic sanctions".
North Korea, meanwhile, has shown no signs of abandoning its nuclear and missile programs, maintaining its hostile posture toward Washington.
