LUO YAN sat on his designated station inside the Chemistry lab. Because there were only 20 of them in the class, there's no need to share lab station and thus no need to have lab partners. This way it would prevent incidents of one student doing more than the other. It would also promote critical thinking for each student.
But sadly, he was an exemption to this rule. Because of his situation, the Chemistry teacher thought that it's dangerous for him to handle chemicals on his own. So every time they had to do an experiment, a classmate would be assigned to him as his partner. He wondered who would be assigned to him today?
When the Chemistry teacher came, everyone stood up and greeted him. After they all sat down, the first thing the teacher did was to explain the topic that the class would tackle for today. Then he looked at Luo Yan's direction.
"Since we are going to do an experiment today, I will assign a lab partner for Student Luo first."
Why do you think Yu Jiao had that kind of drawing? ヽ(o^▽^o)ノ
