Okabe:
[referring to the fact that previously, she had stabbed him with a kitchen knife]
I don't understand. Why did you do that to me? Why?
Katsuko Watanaka:
[she looks away]
I wanted... to kill myself.
Okabe:
You mean suicide?
[she nods yes]
Okabe:
But, why did you have to do that to me, then?
Katsuko Watanaka:
I don't know how to say this right. I don't exactly remember... what it was like. Only, when I thought of killing myself, I was afraid you would forget me. I thought... you would forget me soon after I died. I was so scared. So scared. I couldn't stand it.
Okabe:
I had no idea... Let's go eat something!
Katsuko Watanaka:
I'm not hungry now.
Okabe:
Well, then, some other time!
[cheerfully hops on his delivery bike and rides off]
Katsuko Watanaka:
[watches after him with a sad face]
I'm sorry, Mr. Okabe.
