Ebina was much more better because she hate herself because she let hachiman self destruct for her sake and she also feel gratefull to hachiman for all of this.

Spoiler:

It was not just Hayato though: Ebina herself did not want the current relationship between the classmate to change (thus Tobe's confession will fail). Hachiman's solution is one that can satisfy Hayato, Tobe, and Ebina.

Yeah, in some way Hayato did use Hachiman to accomplish what he couldn't/didn't want to do (At one point Hachiman wanted to punch Hayato but held back).

Forgot to add that Hayato's and Yukino's past has yet to be explored.
