On arriving home at the Gu residence, Chu He walked up to the front door, only to find it locked.
???
Why was the door locked?
Generally speaking, the Gu family residence's front door would be kept open even late at night. Moreover, it was guarded round the clock by the Gu family's guards. Now that the door was locked, Chu He was puzzled. She knocked.
She waited for some time but no one opened it. Then she lost her patience and gave the door a hard kick. It responded with a loud boom!
Footsteps could be heard behind the door.
Chu He crossed her arms and waited for someone to open the door. However, a voice from behind the door said, "Is that Big Sister Chu?"
