Gaara and Yashamaru in “Unfinished Business”

Gaara

[looks at his heart] But lately I've felt a lot of pain here.

[Cuts his finger] Wound your body and the blood will flow, following fast on the heels of pain, but as time passes the pain eventually fades away. With the help of medicine it can heal even faster. But even more dangerous is a wound dealt to the heart, because there is nothing that has more trouble healing.

Gaara

A wound to the heart?

Wounds to the heart are a little different from wounds to the flesh. Unlike an injury to the body, there is no medicine for a wounded heart, and sometimes it never heals. But don't worry. There is one thing that can mend a broken heart, but it's a very complicated remedy. It can only be administered to you by another person.

Gaara

So then what am I supposed to do?

There's one thing that can heal the heart, only one. It's love, Gaara.

Gaara

Love?

You've got it.

Gaara

But how am I supposed to get rid of it? What is it I have to do to get rid of this pain?

Don't you know, Gaara? It has already been given to you. Love is a heart's desire to serve someone precious to you, to watch over them, to care for them, like my sister did for you.
