I picked this up after seeing it on a few recommended lists. Time travel stories appeal to me, and the basic premise here is that Naho receives a letter from herself, 10 years in the future. The letter details what happens in Naho's life, and lists instructions on things her future self wants her present self to change. Nifty! 
 While I happily read all of it, I found some of the situations frustrating (just be honest with each other already!) and others difficult to believe. The artwork is nicely done, with clean lines and appropriate expressions. I can also appreciate if this story helps any teens suffering from depression. 
 Still, I'm not moved enough to read any more.
