Gu Zhihan could tell by her expression, "Are you sure you only don't know just a little bit?"
Luo Mengmeng knew she couldn't hide it from him and sheepishly touched her nose, adding, "Okay, I admit it's a bit more than just a little bit!"
"Why didn't you just say you don't know it at all?" Gu Zhihan pointed out impatiently, picking up the pen to continue teaching her, "You're really silly."
"You're the silly one!" Luo Mengmeng, angered and embarrassed, punched him and pushed all the blame onto him, "You were explaining so fast and it was all so complicated, how could anyone remember!"
"Alright, alright, it's not because you're silly, it's because I haven't taught well..." Gu Zhihan took her hand, smiled gently, and took all the blame onto himself.
"That's more like it!" Luo Mengmeng, like a capricious little girl, nodded in satisfaction.
Next, Gu Zhihan deliberately spoke very slowly, and Luo Mengmeng listened intently.
