The door was half-closed.
Xiang Wan delayed for a while before lowering her head and knocking on the door gently.
There was no sound inside.
Xiang Wan pushed the door a little.
There was nobody inside.
She had contemplated about what to say before she knocked on the door but seemed like she had wasted her time.
Bai Muchuan was not inside the office.
She was holding her resignation letter as she looked down at her phone.
"Teacher Xiang…"
Tang Yuanchu came from behind and looked at her in surprise. "You're looking for Captain Bai?"
"Mm." Xiang Wan's finger pointed at the door and smiled at him. "Captain Bai's not here?"
Uh! Tang Yuanchu was about to speak but laughed after looking at her for a few seconds.
"You didn't know that Captain Bai has gone out in afternoon? He and Xie Hui had gone to pay Xie Wanwan a visit to understand more about the case."
