I agree with you 100% on this but I think you missed the whole point of the story. I think it's about cycles of hurt and misplaced feelings. The idea of the story is how could Tamaki be so horrible to Yuu? How could she still be in love with her ex while dating Yuu? How could Yuu put up with such things. The answer is Nagi. When you see things from Nagi's perspective as to how she feels about Yuu, it makes sense for Yuu to accept such treatment from Tamaki and for Tamaki to accept it from Misaki. To the same token that's why Tamaki can let herself be that way to Yuu, because she wanted to accept Yuu's feelings but she was still in love with Misaki. Its not until Yuu sees Nagi try to become Tamaki, copying how she tried to become Misaki, does Yuu understand Tamaki's feelings for her through her own feelings toward Nagi.
The idea behind this story is that at one point they all were and will be each other.
Well, yes it's a story about cycles. And I think the title is thematically relevant, the "onegai" when one of the girls begs the other for something. At first, Tamaki says yes to Yuu, (presumably as Misaki had said yes to her) and indulges her desires, believing or hoping that she can live up to Yuu's expectations (or not taking them seriously, because she kind of acts like a heartless bitch a lot of the time). For the moment, I'll assume that the author was trying to tell us that Tamaki took it seriously, but honestly I think that's a pretty dicey assumption based on how she's presented within the work.
But, as things develop, it's clear that attempting to conform yourself to another person's wishes does not lead to a healthy relationship. Yuu tries to be Misaki so that Tamaki will like her, Tamaki does whatever Misaki tells her to, and Tamaki tries to accept Yuu, for Yuu's sake. So then at the end when Nagi attempts to become Tamaki so that she can be with Yuu, this is a repetition of the cycle. However, Yuu breaks the cycle when she tells Nagi she can just be herself, and that she'll just be herself as well. Presumably Tamaki is still stuck in whatever kind of awful relationship she has with Misaki, but maybe she decided to stop being her bitch, nothing is stated either way.
