Valt: I'm so scared, what if the surgery doesn't work today?

Shu: I know, stay calm.

Valt: I love you.

Shu: I love you more.

(After surgery, the only person in the waitingroom is Diago.)

Valt: Hey, where's Shu?

Diago: Don't you know who gave you the heart?

Valt: *starts sobbing uncontrollably*

Diago: Just kidding, he's in the restroom.
