Information request re: Sayoko's Diary

[otakukeith.livejournal.com]

This entry on the Code Geass wiki piqued my curiosity, specifically with this quote:

"In the first diary segment, which takes place during the sixth episode, Sayoko meets Suzaku for the first time, and apparently has a hint of affection for him. When Sayoko hears Suzaku's voice with Lelouch, she tries to call him, but overhears them saying that they should not been seen together, so that nobody will know about their relationship. Sayoko thinks that Suzaku is romantically involved with Lelouch, which completely devastates her."

Can anyone shed any light on this? Is Sayoko upset at thinking Lelouch is gay/unavailable, or Suzaku, or both? I fear I'm being afflicted with Sayoko/Lelouch and Sayoko/Suzaku fanfic plotbunnies...
