She can't be serious. Hiro was amused with Berlin's reaction.
He didn't know whether she was inherently shy or if this was a byproduct of the church's teachings.
"I'm just being polite, you don't have to mind it so much," Hiro waved his hand dismissively and looked around. "We should hurry up. The sooner you reunite with your peers, the better."
Hiro only exposed himself to prevent the girl from killing herself, he wasn't planning to stick to her side from this point onwards.
Berlin calmed down, and after giving the broken spear a reluctant look, she fixed her disheveled hair and turned to leave.
She wanted to tell Hiro not to follow her and that she'd be fine on her own, but the words wouldn't leave her mouth.
Then, she gritted her teeth and chose silence.
As in, she didn't start a conversation with Hiro nor did she respond to his initiative. After figuring that out, Hiro also stopped talking with her.
