Listening to Lin Siran's words, Xu Yaoguang looked at Qin Ran, who was holding her head irritably and spinning a pen around. He was such a calm and composed person, yet even he couldn't react in time.
"I couldn't do this question. But when I was submitting it, Ran Ran helped me fill it in." Lin Siran seemed to see that Xu Yaoguang was surprised and tilted her head to explain.
Physics wasn't the same as Chinese, especially when filling in the blanks. This question was impossible to even start solving and time was tight, so Lin Siran had just given it a glance and skipped it.
When she handed in the paper later, Lin Siran didn't even do many big questions, so how could she worry about filling in the blank questions?
Lin Siran felt that Qin Ran had obsessive-compulsive disorder. She filled the paper up every time and didn't leave any empty blanks, and couldn't even bear to see her leaving an empty question down.
