When they met for the first time, Gong saw Shou dumping his cousin in a very gentlemanly manner.
When they met for the second time, Gong found out that Shou was his student, and that Shou blatantly acted in his class...
Suffering and anger: "What happened to me not paying attention in class? What happened to me drawing in class? What happened to me drawing two people?!!!"
Gong smiled: "Not really, everything you did is right. However, as a professional, I want to have an in-depth discussion with you about 'that', because I found that many of the things you drew are unreasonable."
Suffering, anger + panic: "Go away, pervert!"
Attack: "Hehehe..."
