Lin Zhiruo (struggling to get up from the dense papers): Maybe triangles have stability.
Pan Xinyue, Wang Wenzhuo (rushing towards them, covering their mouths): Shut up! You math prodigy!
(If you are a novice writing an article, I will just fill in the size thing and you can take a look at it)
Intention: friendship, reality (you and I both had difficulties in what happened back then, I don't blame you)
