On the graduation from the kindergarten, Yuzuha told Makoto that she likes him a lot, but Makoto told her he didn't like her. That made Yuzuha to start crying and seeing that Takeo told Makoto to not make girls cry. As Makoto apologized, Yuzuha stopped crying and with happy face saying it's okay.
Both used to be in the same kindergarten. Takeo was in love with her, but she didn't share his feelings. As she was turned down by Makoto, it's likely that she was badmouthing Takeo.
