Levi couldn't believe that Emma would ask him to meet him so soon. Apparently, his feelings for her were greater than her feelings for him.
Even though it was disappointing, Levi decided to accept the reality. Emma rejected him and only wanted friendship, exactly what he wanted in the first place. Therefore, he would do as Emma wished.
For Levi, while he could still meet Emma, see her smile, and talk casually with her, that was more than enough.
"I will face a war," Emma said flatly.
Levi frowned. Then he chuckled, "A war?"
Emma nodded slowly. "Let's just say it's a war,"
"I see. So, are you afraid to face it?" He asked, deciding to take Emma's game. Maybe the war was a parable that Emma used for the very difficult problem she was facing.
"I don't know whether I'm scared or not. But, I feel worried for sure," Emma answered.
"It's normal to be afraid and worried before facing something big. It doesn't mean you're weak." Levi said.
