This structure is something new from you, which left me a bit hesitant of diving in as it seemed long with a lot of casual conversation. But I think your set-up kept me going. The flashback of 4 years ago, followed by the end of it; then by my surprise you kind of went into the future while simultaneously going into the past, now 3 years ago. Little things like these make the reader want to read on, as it sets up an expectation of the story yet with unknown directions.

That being said, my curiosity kept me reading but I think I would've enjoyed this write more if you showed the pain more rather than bluntly writing down the dialogues. I understand that this is part of the structure you had in mind, but a little imagery here and there would spice things up a bit.

"she had placed the nails deeper in her dead heart"
^ This line, for example, was refreshing for me to read because it truly expressed Moria's emotions rather than her simply saying she was hurt.

"Her shattered heart I tried to piece together even as it cut into my skin, she was worth the pain."
^ Another line that sparked my interest. You did mix up some casual every-day speech in it ("she was worth the pain") but I think it added up nicely with the abstract image you painted before saying that. I think it's all just a matter of balance, I'm not telling you to get rid of this dialogue-language all together, just to mix it up a bit with other means of expression.

Besides those lines I pointed out, your choice for the name Athena interested me because near the end I was compelled by the tone of your story. It felt very archaic due to its sacrificial nature and the introduction of seasons. I thought it fitted very nicely as the ending seemed to become more dramatic, reflecting the depressed and hopeless state of the persona. I think the inclusion of coldness and winter made it easier for you to paint the feelings, it's emotive.

Keep writing,

Moira,

This is a quite surprising piece by you and very enjoyable. I really enjoyed the use of text and flashbacks, very original.

Take care, Em
