I personally think that Onodera was confessing her feelings for Raku because she felt that she'd lost against Chitoge, but if she'd confessed after Raku and Chitoge (supposedly) got together, it would have been seen as even more disrespectful. Onodera may not have been the most tactful when confessing but I think she needed to let her feelings out no matter how unconventional may it be.
WHY ARE YOU CONFESSING AND RIGHT BEFORE HE GETS TO CHITOGE!? ヽ(`Д´)ノ YOUR JUST HOPING HE'LL PICK YOU BECAUSE YOU ARE THE "PROMISED GIRL" YOU DON"T CARE AT ALL ABOUT CHITOGE"S FEELINGS!!! (╬ ̄皿 ̄)凸 COME ON RAKU YOU KNOW WHO YOU TRULY LOVE AND IT IS NOT DEVILDERA!!
