Chrystal Zhu looked at cookie Hua and felt like something was off in her. Since they were just walking, she nudged her to gain some attention. But Cookie Hua seemed to be absent-minded as it felt like she was thinking of something.
Chrystal Zhu did not know what to do. She was a little stuck up because she wanted Cookie Hua to wake up and walk properly but on the other side, she did not want to stop her from thinking something new to keep her brain active. But both of them felt a little important so she gave a little consideration on what to do next.
Finally, Chrystal Zhu held on to Cookie Hua's hands because she did not want her to get any hurt while being with her. And if Cookie Hua woke up from her thoughts, then she was not worried at all because the main purpose is all about her safety before an accident.
