Hinata: Even if you can't walk or stand, or even if you can't have kids! I'll still marry you! I'll always stay by your side. The Yui I met here isn't fake. It's the real Yui. No matter where or how I meet you, I'll fall in love with you. If I can meet you again, against the 6 billion to 1 odds and even if your body can't move, I'll marry you.
Yui: We won't meet... I'm always in bed at home.
Hinata: I play baseball you know. One day, I'll smash a baseball through your window and when I go to get it, I'll find you. That's how we'll meet. We'll end up talking, we'll get along, and before I know it I'll be visiting you every day.
It's a part of the dialogue between Yui who was paralysed since she was 3 years old in life and Hinata an older boy which she met in the afterlife. It gets me every time. For the whole scene click here!
