She first meets Ken who is the Digimon Emperor, one of Myotismon's pawns. At first, she was dissapointed that Ken will not show up at her soccer game. After Ken breaks free of Myotismons strings thanks to Wormmon's sacrifice to save him from Kimeramon and joined the new digidestined. After the final battle, She and Ken began a romantic relationship.

It seem Yuri one of the Russian DigiDestined also thought Yolei was pretty cute, meaning that he also crushed on her, Yolei said that she should have brought him has a Russian souvenir, maybe having feeling for him too.
