May Lee is introduced in The King of Fighters 2001 as one of the many students of Kim Kaphwan, and has always worshipped him and Jhun Hoon since she remembered. One day, during the training, she heard the news of the King of Fighters tournament. As always, the South Korean team (composed of Chang Koehan, Choi Bounge, Jhun Hoon, and team leader Kim Kaphwan) will enter.
However, Jhun injured his leg due to a street traffic accident and May Lee had to replace him as a member of the Korean team. Kim suggested that she would also pay attention to her teammates, former criminals Chang Koehan and Choi Bounge. For Chang and Choi, as May Lee, unlike Kim, he feels that there is no need to corporal punishment on a regular basis.
Despite her lack of experience, May Lee surprised the audience with its unique Taekwondo style during the tournament. Kim and others were also amazed at her achievements, and she quickly gained a lot of praise. After the tournament, May Lee will return to Korea with her partners and be called a heroes to end the threat of the evil NESTS cartel working behind the tournament.
