> I really adore Luyoon for some reason and when I read this fanfic, my feels for them quadripled. This isn't a really fluffy story, it's very very very angsty and sad and I like that. It really has something behind it, a meaning, and once you get the meaning I think you'd want to hold onto your friends longer and not take them for granted. This story really inspires, and it's so well-written that I just had to put this on here. 

(+) the story will really get to you, because the plot is just spot-on and the grammar is really great. 
(-) I think the writing style might put some readers off, as it is in a letter format. "Dear Yoona... sincerely, Luhan." it's something like that, and maybe some will be skeptical about reading it. So, yeah, fair warning.
