Fu Shinian pulled up a video on his phone and showed it to Su Mu, where she saw President Huang adding some white powder into the wine bottle in his hand, and after doing so, he walked over to Su Mu with that bottle.
The memories from last night returned, and Su Mu recalled how President Huang had spoken so much to her, suggesting they bury the hatchet over a drink. Since Su Mu had been to the restroom earlier, she didn't trust that the drink in front of her was the same one as before, so she poured it out and asked President Huang to pour her a new one. At that time, she felt smug seeing his disappointed reaction, thinking it was all an act to make her feel completely safe.
After the video finished playing, Fu Shinian put his phone back casually on the nightstand and said to Su Mu, who was still somewhat dazed:
"What are you thinking about?"
