Guau este fic fue increible asi me imagino el amor de cecil y rosa ya que en el juego son estrechos ambos pero a cecil le cuesta expresarse lol.

Ahhh! I keep reading this story over and over again I love it so much!
Very well written and just wonderful! :D

Well, I have read your story, and I am honor-bound as a fellow writer to review.

Overall, I think this is a really good piece of work. I didn't see any problems with the grammar.

Per my honor, I am also obligated to review honestly and fairly, and this review would be neither of those were I not to point out a few issues.

There could be a little more description in the narrative, I think. For instance, You might describe the fire or moonlight gleaming off of Kain's armor, or Cecil's/Rosa's heart pounding as they interact in the scene between the two of them. Perhaps, describe how it feels to Cecil as he and Rosa kiss, how her lips feel, or if he could taste her breath, etc. Just remember not to go overboard with description. I certainly didn't see that as a problem here, but you also don't want to give them too little, which I feel you may have bordered on.

Here's something that comes to mind in light of this.

You wrote:

As for Cecil, the Paladin, he could only stare at the fire, his eyes lost in the ever-rising flames.

I can say a few things for this. Staring at the fire and his eyes lost in the fire are essentially the same thing, so you could omit one of them and make the story read a bit smoother. This goes hand-in-hand with the A technique "show, don't tell." "Staring at the fire" is directly telling us he's staring at it. "His eyes lost in the ever-rising flames" paints a clearer image of what this looks like and SHOWS us he's staring at it. Adding a little more description, you could re-write the passage as such:

As for Cecil, his eyes were lost in the ever-rising flames as they warmed the paladin's face with their glowing red light.

I love Final Fantasy IV, and I think the strongest point of this fic was the dialogue. The interaction between Cecil and Rosa was tight, believable and entirely captivating. I actually felt like I was reading the text go by in a scene from the game itself.

There was an issue in the scene, however, that I would like to point out.

You wrote: He took her hand slowly, and she gently pulled him into the moonlight with her, pulling him out of the darkness of the cave and into the moonlight.

You stated twice in this paragraph that Rosa pulled Cecil out into the moonlight. One of these instances is unnecessary. Omitting it can make the story read better.

This can be edited as: He took her hand slowly, and she gently pulled him out of the darkness of the cave into the moonlight.

Keep it up, your dialogue is fantastic and feels like an exchange that might take place from the game itself. I really enjoyed this!
