When Gu Xi was still a top student in elementary school, his painting style was like this - "These linear equations of two variables are roughly solved like this. He Yuzhou, do you understand? He Yuzhou! I'm talking about the topic!" He Yuzhou held his face and stared at Gu Xi with a silly smile (not looking at the topic)
After He Yuzhou succeeded in stealing the teacher and Gu Xi accidentally became a scumbag in physics, the style of painting changed again - Gu Xi got the physics test paper that had just been handed out. Every wrong question on it had a sticky note with the answer, and she knew that He Yuzhou had used his private rights to correct the test paper for her in advance...
