I'm not even sure if she's aware of Chitoge's real feelings for Raku after they all found out that the relationship was a fake. She could do both, cheer him on while confessing
Yeah, you're right! In the chapter 214 we see that indeed, Onodera didn't know that Chitoge loved Raku too. She just wanted to cheer Raku up and talk about Chitoge, she's not "devil". I don't know why people hate her so much (I'm a Chitoge shipper, but that doesn't have anything to do with hate, or at least it shouldn't T^T)
Yeah, I'm all for Chitoge and even though I don't care for Onodera, I'm not going to make her out to be something she isn't.
Whenever I read chapters like this I get so frustrated... My kokoro hurts. Raku and Chitoge need each other so much at this point of the story and they don't even know lol.
I hope he figures this out and goes with the others to search for her in summer break. And then, the last arc about the conflict between the yakuza groups... Ah, the drama melts my heart, what can I do ╮(￣▽￣)╭
Also so funny the Onodevil-san. xDDD I believe that she's trying to cheer Raku up and doesn't want to get ahead of Chitoge while she isn't there... at least I hope so, but... We'll see, can't know for sure yet. T^T
