Glad I met you, Towa. Will always remember you.

[For...however long he has left. Something hurts, and not just at the thought of his limited future - he....doesn't want Towa to be sad. She seems sad, and he's sure it's because of him. He's messed up--

No....he should do what he can to fix himself. To try and treat himself the way the other people on the train have treated him. Right?]

....don't have anything to give you in return, though.
