Kim played a decisive role in securing a ticket to the 2020 Tokyo Olympics in the Asian Continental Qualifiers held in Nakhon Ratchasima, Thailand. The exhaustion built up from the Turkish League had led to abdominal pain during the match against Kazakhstan in the pool stage. She was diagnosed with a torn abdominal muscle and missed the semifinal match against Chinese Taipei. However, the captain reappeared in the final match against Thailand and was brilliant in the win that secured a Tokyo berth to her team. After the game, she admitted that she did not feel well and that she played after previously taking painkillers.
