i think the texter was either Manaka, Chi, Sayu, or Akari

Great story

This was really sweet. I also think you did a great job handling Manaka's position. While you didn't go into too much detail, you gave her a very believable reason to be out of the picture. My bet on the mysterious texter is Sayu or Manaka herself.

Anyway, I know the story on here says complete and that it's been a while since this was written, but it'd be really awesome if you could continue this. It's such a great setup so far it feels like we're missing out on a really good story if you don't. It has a really promising premise, and even ties into the whole theme of change the show had. Everyone feels very in-character and the entire situation is very believable. Add that to the fact that this is a gem among the precious few NNA fanfics and is HikarixMiuna at that, it'd be great if you could continue. It's totally up to you of course, but it'd be really really awesome if you did.

Again great story, and hopefully it will be continued.

A wonderful, heartwarming and well written piece of work, thank you so much for the time and care you clearly invested in this. While there isn't much I feel I can say that hasn't already been said in these comments, and while I'm not sure you'll ever actually read this, I want to express my gratitude none the less. Keep up the good work!

This was amazing. I ship these two so hard, and the feelings they felt for each other in this fic were so genuine. Really like the way it was put across too.

Wow.

I loved it!it was so cute,so detailed, and the descriptions were excellent. Plz make more! To bad that this anime has barely any fanfic ;c

This was really nice. I always loved Hikari and Miuna as a pairing all the way back during episode 6(?) when Hikari picks Miuna up from underwater. He always seemed to be so much more at ease with her. But nothing has ever stopped true love, I guess... other than death of course. I really enjoyed that you were able to take an open ending and build in a backstory into your fic anyways. It made the current events a lot more effective.
The mystery caller, huh? My money's on Sayu, but it could have been Manaka, she's always been a very caring person and it wouldn't surprise me if she tried to get Miuna to hook up with Hikari.
Overall, I'm happy to see a non Tsumugu Chisaki fic for once, and a good one at that. Thanks for writing this.

Amazing! besides seeing these two together, it was really interesting (and a bit sad) to read your take on how/why Manaka/Hikari didn't work out, though it seems to fit with her character rather well.
Pretty sure mysterious texter was Sayu, eh?
