Sanae calls herself an "omoshiree onna" or "interesting woman." This is an often-said line made by male love interests in shoujo romance stories after their initial encounter with the female protagonist.
Common set-ups include a male protagonist that's used to being popular with women but a female protagonist that's not interested in him at all, either due to something about him that puts her off or her perhaps being interested in something else entirely. Or the male protagonist being a genius that's set in their ways and has no interest in others, with the female lead being an eccentric or unpredictable person. When the two characters meet at the start of the story, these differences between the protagonists are made clear, and the male love interest might mutter to himself afterwards "What an interesting woman", thus starting the romance.
The long and short of this is that Sanae likes shoujo.
