Bong Nan Hee (Park Soo Ae) and Byun Hyung Tae (Lee Jung Jin) have been best friends for 30 years. They cook for each other, call each other almost daily, bicker like siblings, and support each other when things go wrong. But all that is about to change.
On her 30th birthday, Nan Hee hits a mid-crisis: she is 30, unmarried, and without a successful career, and her dream of getting published in the city’s spring literary festival has just been crushed yet again. Topping it off, she’s dating a 22-year old baseball player who’s still in college, and beginning to have serious doubts about the ethicality and dignity of the relationship. When Nan Hee decides that it’s time to change her life and move out of her mom’s house, she jumps at the chance to rent Hyung Tae’s house while he goes on vacation. But what was meant to be a short stay turns into a more permanent sort of thing when Hyung Tae returns unexpectedly, having lost all Nan Hee’s rent money, and she refuses to move out until he pays her back. As the two best friends live together, they begin to discover things they never knew about each other but will they discover what their friends and family have suspected all along?
Despite its title, 9 End 2 Outs is not about baseball, but the unexpected miracles that can happen in the 9th inning of the game of love. Hyung Tae is a player not looking for marriage, while Nan Hee is a woman looking for romance everywhere but at him. Park Soo Ae and Lee Jung Jin have incredible chemistry together as the funny, squabbling, in-love-without-realizing-it pair of best friends, and 9 End 2 Outs is that rare, adult, heartwarming story about two people who can’t see what’s right in front of their noses.
