Morocco are also looking to pick up their first points of the tournament after suffering a heavy defeat to Germany in their opening game.
Match preview
South Korea's hopes of reaching the knockout rounds were dealt a blow on matchday one as they fell to a 2-0 defeat to Colombia.
Catalina Usme gave Colombia the lead from the penalty spot, before Linda Caicedo added a second before half time with a long-range strike that slipped through the grasp of Yoon Young-geul in the South Korean goal.
With South Korea unable to find a way back into the contest, they fell to their fifth consecutive defeat at the World Cup finals.
South Korea boss Colin Bell will know that another loss on Sunday would result in an early exit if Germany and Colombia play out a draw.
However, they will have their sights set on claiming their second win at a World Cup finals, with their only previous victory taking place against Spain in the 2015 tournament.
Meanwhile, Morocco will have to pick themselves up for Sunday's contest after beginning their first-ever Women's World Cup campaign with a 6-0 loss to Germany.
The Lionesses of Atlas trailed by two goals at the break following a first-half brace from Alex Popp, before Germany moved through the gears in the second period to net four more goals and condemn Morocco to a heavy defeat.
Having failed to win any of their last six games, Reynald Pedros will be concerned by the fact that his side have failed to find the net in all six of those matches.
With South Korea sitting 55 places above Morocco in the FIFA World Rankings, the 2022 Africa Cup of Nations finalists know that they have their work cut out to get a positive result on Sunday.
Morocco could be eliminated with a game to play if they lose to South Korea and the other game in Group H finishes all square.
