Yano: If I could change my past I will do it, if that will make you stop crying. I wish I could but I can’t. What we need to do is to make the past pale in comparison with the present.

Nana: What kind of present would that be?

Yano: A reality where I exist and you’re right there next to me.

[Bokura Ga Ita]

Sometimes, there are things in our life that aren't meant to stay. 

Sometimes, change may not be what we want, sometimes, change is exactly what we need and sometimes, saying goodbye is the hardest thing you think you'll ever have to do,

but sometimes, saying hello again is the thing that breaks you down and makes you more vulnerable than you ever thought possible.

Sometimes, change is too much to bear but most of the time, change is the only thing saving your life.
