KueKyuuQ, I think you're generally correct. As we saw so far, Aki was holding her feelings all the time and was 100% supportive of Yori, so she couldn't stand seeing how much Yori was suffering and how Himawari was being indecisive. You could say she got "angry" in Yori's place and pushed Himawari to give Yori a proper answer faster instead of continuing on giving her hope. She got impatience for Yori's sake.

Yeah, this is an example of how to do a love triangle that doesn't feel like shoe-horned in bullshit. It's predictable but it's not just predictable because it's cliche it's predictable because it was actually foreshadowed properly instead of coming out of left field for the sake of lazy shock value.
Yea, though I meant more specifically that unlike usual love rivals that often treat it like competition and don't mind using dirty tricks, she's presented as good person who would be a genuinely good match for Yori. Despite clearly being shown as not a treat to main relationship from the start, she still is so likeable you kinda unwitting start rooting for her. Sure it wouldn't work if Yori and Himawari were already going out and it's not only way to do it, but it definitely feels fresh.
The fact that Aki is actually a sympathetic character in her own right rather than an annoying antagonist whose just there to cause problems definitely contributes to me giving a fuck about this situation rather than just rolling my eyes and dropping the series until the arc is finished like I usually do with this trope. She's actually a believable character acting like a sane human being would rather than like a plot device.
