Subaru: Tsukasa! I'm so glad.
Tsukasa: Glad? About what? What are you saying now? There's nothing to be glad about. You abandoned me. Don't you remember?
Subaru: What are you talking about?
Tsukasa: I see. Maybe I was the one who did the abandoning. Human emotions are negative in the first place. This way is more advantageous for survival. Do you understand?
Tsukasa: If you try to think positive, you're always betrayed. You end up in a worse state. I've had enough of that, so I'm ending my involvement with you.
