As soon as Kong Jia returned to the dormitory, the three roommates looked at her and smiled. Someone shouted: "Kong Jia, you took Professor Yan's elective course again today!" She did not answer, but said to the photo of Professor Yan posted on her desk: "Professor, I am back, and I had a good meal today." She sat down on the chair. They shouted loudly and deliberately: "You must not have dared to say hello to Professor Yan!" Kong Jia opened his eyes and said, "Why do you accuse someone of innocence out of thin air..." "What innocence? I saw you face to face with Professor Yan the day before yesterday, and you ran away with a red face. You were not beaten." Kong Jia blushed, and his forehead The veins on his face burst out, and he argued: "Being subtle can't be considered cowardly... Being subtle!... Can a scholar's love be so straightforward and explicit?" The words that followed were difficult to understand, such as "sapiosexuality" and "Platonic", which caused everyone to burst into laughter: the air inside and outside the bedroom was filled with joy.
