Not a simple man (1)

A small house with faded blue painted house looked very serene under the sunlight. Spurred by her worry, Li Caiyi opened the gate urgently and walked briskly to the front door.

She knocked on the door several times, but no one answered. This situation reminded her about the previous times she came here to find Dai Zhiqiang. 

"As expected, he isn't home," Li Caiyi muttered to herself. The time showed 8 AM, so Dai Shenqiang must have already left for school around this time.

Once again, her search ended up with nothing. Confused and tired from experiencing anxiety, Li Caiyi crouched in front of the door facing the gate, thinking about what her following action should be.

Judging by the situation, it was less likely that she would find Dai Zhiqiang soon. Should she leave behind a message and go to K city without him?
