When Zheng Tan arrived, the man was working, with several books spread out on the desk, essentially the same as the last time.
After placing a warm cup of milk in front of Zheng Tan, the man sat back down at the desk and resumed his work.
Zheng Tan looked at the paper cup holding the milk, freshly taken out of a packaging bag, which was one of the reasons he held a favorable impression of this man—the man never used a dirty cup for milk, even though Zheng Tan now appeared to be just an ordinary cat.
After finishing the milk, Zheng Tan didn't disturb the man and walked around the room.
Compared to last time, there was an additional pencil sketch in the room next to the bookshelf. It was colorless and depicted several children surrounded by plum blossoms. There was a date in the lower right corner of the drawing, which was from the day before yesterday.
Zheng Tan was observing when the doorbell rang.
