Shen Jingming taught the students on behalf of the professor, and the originally boring Mao class became lively because of the discussion of several girls. Jiang Chun leaned back in his chair, his eyes half-closed, and suddenly heard a whisper from the back row. "WOC, what do you think is that senior on his neck?!" A voice asked excitedly. "It can't be a strawberry, right?! Was it so intense last night? Another voice chimed in. There are many mosquitoes in summer nights, and there is a high probability that it is a mosquito bag. Jiang Chun opened his eyes suddenly, and his heart chuckled. Oops, she forgot to put concealer on this senior. She hurriedly turned her head and echoed: "Yes, yes, yes, a senior is such a calm and self-contained person, how can there be anything else on his neck, it must be a mosquito bag." ” Suddenly, a chalk head flew over and landed right on the podium. Shen Jingming turned around and saw Jiang Chun's nervous appearance, and the corners of his mouth hooked up with a smile. "Don't worry, it's just a mosquito pack." He whispered. Jiang Chun breathed a sigh of relief, the two looked at each other and smiled, and the atmosphere in the classroom became relaxed.
