They created a unique atmosphere in the Gangneung Ice Arena during the speed skating heats.
Provided there are no overwhelming security concerns presented, it seems likely that Moon will indeed accept the invitation from Kim, delivered both on paper and via personal invite from the younger Kim present. The country conducted several weapons tests past year, sparking a war of words between US President Donald Trump and North Korean leader Kim Jong Un.
Vice President Mike Pence said Saturday evening there is "no daylight" between the US and South Korea, despite their different approaches to engagement with North Korea at the Pyeongchang Olympic Winter Games.
"There is no daylight between the United States, the Republic of Korea, and Japan on the need to continue to isolate North Korea economically and diplomatically until they abandon their nuclear ballistic missile program", Pence said in comments carried by CNN.
"I am very confident, as President (Donald) Trump is, that President Moon will continue to stand strongly with us in our extreme-pressure campaign", Mr Pence told NBC in an interview, maintaining all options were open to deal with the crisis.
Already there have been concerns that North Korea's overture of the sports diplomacy is an indirect attempt by the regime to wedge a rift between the United States and South Korea.
Tensions between the two soared past year as Pyongyang launched intercontinental ballistic missiles capable of reaching the USA mainland and carried out by far its most powerful nuclear test to date.
They expressed scepticism on the prospects for a summit, with professor Koh Yu-hwan of Dongguk University not expecting one "in the foreseeable future".

The US president is also withholding tens of millions of dollars from UNRWA, the United Nations agency for Palestinian refugees. PM Modi will visit Oman for the first time as prime minister and will hold talks with the Sultan of Oman and other key leaders.

Pence and Moon were expected to view men's short-track speedskating together prior to the women's event, as an American and a Korean were competing against each other, but Moon kept Pence waiting and missed the event entirely.
Fans roared every time a Korean got the puck on her stick and Han Soojin almost put the team on the board with a shot from the left circle that hit the crossbar early in the first period.
We are far from the only ones to spot this similarity.
Moon was all smiles as he greeted Kim Yo Jong, the sister of North Korean leader Kim Jong Un, and Kim Yong Nam, the country's 90-year-old nominal head of state, for lunch at the presidential residence.

The rare meeting at the Blue House in Seoul on Saturday comes after Kim Yo Jong and other North Korean delegates attended the opening ceremony of the Pyeongchang Winter Olympics where they took their place among dignitaries from around the world, including U.S. Vice President Mike Pence.
Regardless, both Pence and the North Korean officials can return home and claim they did what they came to Pyeongchang to do. "The world cannot turn a blind eye to the oppression & threats of the Kim regime".
The smiles and handshakes were friendlier than some of the North's past history with the complex - in 1968 Pyongyang sent commandos to attack it to try to assassinate the South's then leader.
