Why is he angry?
When A Qi returned with the surveillance footage, she found Su Qingnan sitting at the door, holding her head in her hands, lost in thought.
"Young Madam." A Qi looked at her puzzled, "What are you doing sitting at the door?"
Su Qingnan quickly stood up, patted her pants, and said helplessly, "He locked the door from the inside, I can't get in."
Startled, A Qi glanced at the door, and cautiously asked, "Is the Eldest Young Master angry?"
"...Probably?" Su Qingnan helplessly pressed her forehead, "I've been calling him ever since I got back, but he won't respond to me."
"Then he's definitely angry." A Qi affirmed confidently.
"Alright then…"
Glimpsing at the lock, Su Qingnan's eyes suddenly lit up, she looked at A Qi: "A Qi, you're the Eldest Young Master's bodyguard, you should have a key, right?"
A Qi shook his head: "No."
"Really nothing?" Su Qingnan didn't believe it.
