I can't walk anymore

Hikaru glanced at Aiko, and upon seeing that she was smiling naturally, without any pretense, he felt a little… uneasy.

He waved his hand and said: "I am not thirsty, you should keep it to drink. In the apocalypse, supplies, especially food, are precious, so use them sparingly."

Aiko held a hint of sadness in her eyes, however, she kept a smile on her face, nodded and said, "Um… I know. Thank you for reminding me."

Then, she suddenly glanced at Laylah aggressively.

Although that gaze was only for 1 second, Laylah easily recognized Aiko's gaze.

No one would have thought that a girl with an innocent appearance like Aiko would have such  sharp eyes like a murderer.

She shook her head and sighed, stood up and said, "You sit with him, I'll patrol around a bit."

Hikaru was confused when he heard that this was not the place he wanted to stay, so what was she patrolling for?
