[ It wasn't that long ago when Nico lived in the mindset that he could do everything on his own. He is acutely aware that slipping back into it could happen so easily. So he doesn't dismiss someone worrying about him, there may come a time when he seriously needs someone to talk sense into him.

They haven't known each other very long, but Chizuru seems to be someone willing to do that. Maybe it was something that happened with the Shinsengumi, that she couldn't much about. ]

If it gets worse or I need help, I have someone I can talk to. Can go to if I need it. He's knowledgeable about health and biology things, and I trust him.

[ His fixes a serious gaze on her. ]

And if I ever get stupid about not accepting help, you are always free to point that out to me. Because we're friends.
