Comments of My Tomorrow, Your Yesterday

I just watch the movie

Is the secret that she can read minds? Idk imma watch the movie I guess

since i already watched the movie, i know what's coming and what that "tragedy" tag means
im so happy it got a manga adaptation even though the movie was so amazing, hopefully it will also get an anime cause it's worth it

Can anybody tell me why there's a tragedy tag?! I don't want to cry after reading it
