This is heartbreaking beautiful. I like the way you wrote it a lot. It's filled with so much emotion and it just all flows very naturally and wonderfully. I love the overwhelming sense of regret in this piece and how she realises she made one of the biggest mistakes of her life but can't fix it. I wish she would've made more of an effort for him since she clearly still loves him, but I also think he's been so hurt by her rejection that he wouldn't let her back in.
I don't know why you said you're horrible at writing stories because this is a stunning one-shot filled and it's very poignant as well.
I liked it. The layout was lovely and really added to the story.I feel bad for her though, wanting to take that last action and not being able too...I like how you incorporate the song, but not to much. You did a really good job of that.
I really liked that, sometimes I don't like when short stories relate so heavily to the song but you worked it really well and it was really good. I enjoyed it!
