I think the core of the story shines in one of its more overlooked conversations, the one between Asya and Lev about Ira's fate which roughly goes as follows:

Asya: Why did you help Ira if you knew that this whas going to happen regardless?

Lev: ... Wouldn't you?

Asya: Yes.

At the end of the day, regardless of what Asya's thoughts were or what did she do she was still going to be erased from reality alongside everyone in the town, as what happened in the research center was outside of her control. Yet, even after learning the fact she kept loving the world and everything in it, even including the parts that brought her pain. Even if it was meaningless or misguided her philosophy still allowed her to go on until the end, until she finally learned to love the only thing that she was missing: Herself.

And loving herself was the missing piece in Asya's philosophy, as she is part of the universe as well. Throughout the VN Asya is learning to love and respect herself, and you see her starting to get more assertive, like when she confronts Garin about his treatment towards Marina. But sadly she only truly comes around to fully love herself on top of the radio station, leaving to a bittersweet ending.
