They did not notice this previously because they were misled by the reporters' interview footage.
Wu Huai had initially assumed that the interview footage was shot continuously.

Wu Huai managed to confirm this through the website and the broadcasting station. A three-minute advertisement was being shown at that moment indeed.
"In other words, all three of you drank the first batch of coffee together, but Yuan Zhe drank the second batch by himself once it was refilled?"
"Yes, that's right!"
