“完了……这次真的完犊子了。”

高二（三）班教室里，王磊感觉自己的脑壳被一台拖拉机开了过。数学试卷红叉子比汉字还多，选择题大半是蒙的，大题一个没写对。窗外的夕阳正好，可他盯着试卷上的分数，感觉那阳光都带着嘲讽的意思。

“喂，王磊，发什么呆呢？是不是昨晚又熬夜打游戏了？”同桌李昊东推了推鼻梁上的眼镜，语气里带着点调侃。

王磊苦笑，赶紧埋头把试卷塞进抽屉。数学老师马老师是个出名严苛的“灭绝师太”，这次月考他必须不及格，((-1) * ∞ ≈ 0)。

Copies of the math test with multiple-choice questions and large problems were scattered on the teacher's desk, and several students were handing in their work one after another. The classroom was filled with the smell of franchised instant noodles and dust.

突然，教室后门传来一阵骚动。几个同学探头探脑，神神秘秘地讨论着什么。王磊皱了皱眉，没太在意。

“哟，看什么看？新来的转校生啊？听说是个大美女。”李昊东压低声音，神秘兮兮地凑过来。

王磊扒开人群往里瞅，眼前的一幕让他愣住了。

门口站着个女生，个子高高的，穿着一身简单的白裙子，扎着马尾，阳光洒在她身上，整个人亮得晃眼。她手里还抱着本书，封面是灰扑扑的旧书皮，看得出来是本古籍。

女生似乎没注意到教室里的嘈杂，自顾自地走到讲台，放下书，然后开始掏自己书包。 Classes typically started at 8:00, but it was already past 5:00, and this mysterious girl seemed to have little regard for the time.

“新同学？报道啊！”马老师提高了音量。
