Haru-chan... He likes to try and deal with things on his own. He always comes around, though. The best you can do is just... let him know you're there and wait.

Mako-chan's better at it than I am. I get really impatient and try to bug him.

...Rei-chan's a lot like Haru-chan, I think. [Which worries him. Because he's not Mako. He's not good at just waiting.]
