Why did Oyuki flirts with Ataru ?

Manga Volume 01 - Chapter 10 « Oyuki »

Season 01 - Episode 06 (2022)

I know I shouldn't get hung up on a work that's primarily a comedy, even a parody, but I'd like to know what motivated Oyuki to seduce Ataru. Unlike Benten and Ryoko, who did it for strategic and Machiavellian reasons respectively, the Queen of Neptune seemed to genuinely enjoy herself and was disappointed that B-Bo, then Shinobu and Lum, ruined the moment. And yet, she never tried to win Ataru's heart again afterward.

Does anyone know why ? Thank you in advance !

P.S. : Sorry for the scans of the manga in Spanish, but I couldn't find any in English.
