「好吧不聊這些啦，我肚子餓啦！」卞芳華一看到上菜，眼睛都亮了起來，剛才那些情緒彷彿被她一口吞下。
「……」曹賢穎看著她瞬間轉換模式，微微怔了一下，像第一次見識人類情緒的極限變化。80Please respect copyright.ＰＥＮＡＮＡqsISWLPqpK
「謝謝你送我回家！要記得喔，有拍攝要找我卞芳華～」她一邊揮手一邊喊，笑容燦爛得像哪裡都不用負責似的。80Please respect copyright.ＰＥＮＡＮＡOoVUwhZpsN
從那天起，卞芳華加了曹賢穎後開始狂傳搞笑影片，有時候是奇怪的動物，有時候是尷尬的綜藝橋段，不管他回不回應，她都照傳不誤。80Please respect copyright.ＰＥＮＡＮＡCeYWzC5wtV
然後，她又慢慢不出現在學校了。80Please respect copyright.ＰＥＮＡＮＡ5vwzqRoqux
直到，她父親回國。80Please respect copyright.ＰＥＮＡＮＡHNoARPIwHw
一如往常安靜的客廳，門卻忽然「喀啦」一聲被打開，卞芳華嚇得從沙發上彈起來，以為遭小偷，抓著拖鞋就要備戰。80Please respect copyright.ＰＥＮＡＮＡkcy8Zp5kri
結果下一秒她看到門口的那張臉，魂差點飛出去。80Please respect copyright.ＰＥＮＡＮＡ1ySm2pQFD4
80Please respect copyright.ＰＥＮＡＮＡMnwfKFjj39
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。80Please respect copyright.ＰＥＮＡＮＡUv6x1JPO6y
80Please respect copyright.ＰＥＮＡＮＡT8TXtHRdkw
「芳華。」父親的聲音一如既往冷冷的，卻讓她瞬間如墜冰窖。「妳怎麼在家裡？」80Please respect copyright.ＰＥＮＡＮＡ2uSn4AgvDQ
80Please respect copyright.ＰＥＮＡＮＡQjb8CDVAnM
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。80Please respect copyright.ＰＥＮＡＮＡ2mcKROKDYr
80Please respect copyright.ＰＥＮＡＮＡ4nnEoOQ5DG
「蛤？」那一聲像審判。80Please respect copyright.ＰＥＮＡＮＡmnOQ923Wcv
80Please respect copyright.ＰＥＮＡＮＡIkTCbrkk6J
「對不起對不起對不起！」她舉雙手投降。80Please respect copyright.ＰＥＮＡＮＡQhs0xKMzZV
80Please respect copyright.ＰＥＮＡＮＡDRZNiXjHaG
「死丫頭！又給我翹課！」怒吼瞬間引爆全場，像打雷那樣震得整棟樓都在發抖。80Please respect copyright.ＰＥＮＡＮＡMf5V4bI6Qs
於是，卞芳華又乖乖回去上課了。80Please respect copyright.ＰＥＮＡＮＡ0FcNoXAmob
但她的成績實在太慘，尤其數學幾乎每次都掛蛋。她爸終於下定決心，特地去拜託曹校長：「你兒子成績那麼好，能不能去我們家幫我女兒補補課？」
「沒問題呀卞兄。」曹校長看在老交情上非常樂意。80Please respect copyright.ＰＥＮＡＮＡmUhaiXLYse
「那就一三五來幫我女兒補習吧，她這些年的成績真的慘不忍睹。」他一臉無奈地搖搖頭。80Please respect copyright.ＰＥＮＡＮＡTsCu0wwcgw
80Please respect copyright.ＰＥＮＡＮＡ0w9eL8vdeQ
「嗯，沒問題。」曹賢穎不多話地答應了。80Please respect copyright.ＰＥＮＡＮＡ13H1uBpUwO
於是曹賢穎開始了他的補課初體驗。80Please respect copyright.ＰＥＮＡＮＡTe3s6XVzob
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」80Please respect copyright.ＰＥＮＡＮＡN3VD1X41fY
80Please respect copyright.ＰＥＮＡＮＡZitQpYW5V2
「嗯，妳好。」80Please respect copyright.ＰＥＮＡＮＡ2AVWMVA3rz
80Please respect copyright.ＰＥＮＡＮＡ9VEJZfdQad
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。80Please respect copyright.ＰＥＮＡＮＡ47NhNZPJgX
80Please respect copyright.ＰＥＮＡＮＡOj7eNWa0bA
「我應該坐哪裡？」80Please respect copyright.ＰＥＮＡＮＡwVI0g47h4h
80Please respect copyright.ＰＥＮＡＮＡ8jy6ZMlxtk
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。80Please respect copyright.ＰＥＮＡＮＡLm8j8HMNa7
80Please respect copyright.ＰＥＮＡＮＡPoIITt64dG
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」80Please respect copyright.ＰＥＮＡＮＡUijqJa4TRx
80Please respect copyright.ＰＥＮＡＮＡ3wJ16MHW3Q
曹賢穎坐在她旁邊，拿出自己的筆電。80Please respect copyright.ＰＥＮＡＮＡOfXnmYmnTW
「嗯嗯嗯嗯嗯！」卞芳華像小雞啄米點頭，活像被戳中心事的孩子。
「我們先從一元二次方程開始吧。」曹賢穎拿出一本一年級的數學課本，翻到一個章節，「妳應該學過因式分解？」80Please respect copyright.ＰＥＮＡＮＡDZzOOtJke7
「呃……我記得有聽過啦……」卞芳華一臉迷茫。80Please respect copyright.ＰＥＮＡＮＡo3FV2BKswS
80Please respect copyright.ＰＥＮＡＮＡQlDtJdJfY2
他舉起筆，寫下：80Please respect copyright.ＰＥＮＡＮＡc51ueXt1ol
80Please respect copyright.ＰＥＮＡＮＡaw8nsy3i9H
x² + 5x + 6 = 080Please respect copyright.ＰＥＮＡＮＡkMIAePkp68
「這題怎麼解？」他問。80Please respect copyright.ＰＥＮＡＮＡhfjDBEJJ5Z
80Please respect copyright.ＰＥＮＡＮＡK4NoehHUTP
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」80Please respect copyright.ＰＥＮＡＮＡn06mEuTWNM
80Please respect copyright.ＰＥＮＡＮＡjjRgw7n0eI
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」80Please respect copyright.ＰＥＮＡＮＡ8pCFtcIOcW
80Please respect copyright.ＰＥＮＡＮＡi41H4j7wuU
曹賢穎寫下：80Please respect copyright.ＰＥＮＡＮＡepUga0gXdp
80Please respect copyright.ＰＥＮＡＮＡ1K5WF20HKc
(x + 2)(x + 3) = 080Please respect copyright.ＰＥＮＡＮＡYlFqcas97w
「所以解是？」80Please respect copyright.ＰＥＮＡＮＡKKvqftY6Mn
80Please respect copyright.ＰＥＮＡＮＡ5ogCdCpDbv
「x = -2，x = -3？」80Please respect copyright.ＰＥＮＡＮＡXUT6CFmNO7
80Please respect copyright.ＰＥＮＡＮＡiLQAtmFGEn
「對，這題妳還可以。」80Please respect copyright.ＰＥＮＡＮＡD2SQj2cEqh
80Please respect copyright.ＰＥＮＡＮＡy1Mm1yNB6S
「耶～」她開心地握拳。80Please respect copyright.ＰＥＮＡＮＡHijLjZHnG2
80Please respect copyright.ＰＥＮＡＮＡBRpEdQKs6r
「那這題呢？」他接著寫下：80Please respect copyright.ＰＥＮＡＮＡOh4xiBsxUh
80Please respect copyright.ＰＥＮＡＮＡlwbPcz7yft
x² - 7x + 10 = 080Please respect copyright.ＰＥＮＡＮＡXbHyHjnOk4
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」80Please respect copyright.ＰＥＮＡＮＡwxtyDCNA56
80Please respect copyright.ＰＥＮＡＮＡaI2p3ncUYC
「不對，5跟2乘起來是10，但加起來是7，不是負7。」80Please respect copyright.ＰＥＮＡＮＡiqDzUbbM5H
80Please respect copyright.ＰＥＮＡＮＡO71cixARx1
「哦哦對齁……」80Please respect copyright.ＰＥＮＡＮＡFuT96mYQwa
80Please respect copyright.ＰＥＮＡＮＡVLhRYHKgOv
「妳不要急，來，我們先列出10有哪些因數組合，再挑加起來是負7的。」80Please respect copyright.ＰＥＮＡＮＡfwVkYNBips
80Please respect copyright.ＰＥＮＡＮＡeSEIPG2UiZ
「……1跟10、2跟5……喔！是-2跟-5對吧！」80Please respect copyright.ＰＥＮＡＮＡb3kCd2w1dh
80Please respect copyright.ＰＥＮＡＮＡNMHbq5k1lv
「嗯，不錯，那妳寫出來看看。」80Please respect copyright.ＰＥＮＡＮＡPrw2dfT2ij
80Please respect copyright.ＰＥＮＡＮＡamBIbhSUb7
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。80Please respect copyright.ＰＥＮＡＮＡNtuwPaSUuA
80Please respect copyright.ＰＥＮＡＮＡk8JYo7Omss
「欸不對啊……我是不是少了什麼……」80Please respect copyright.ＰＥＮＡＮＡjX0VUEWTB9
80Please respect copyright.ＰＥＮＡＮＡM7HJgGd6zE
「沒有錯啊，妳做對了。」80Please respect copyright.ＰＥＮＡＮＡXA94eMp5RH
80Please respect copyright.ＰＥＮＡＮＡhaqsrsXOlP
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」80Please respect copyright.ＰＥＮＡＮＡxmcfJe1mlL
80Please respect copyright.ＰＥＮＡＮＡim3is6X8cV
曹賢穎看著她像孩子一樣開心地在沙發上轉圈又繼續出題：「那我再出一題。」80Please respect copyright.ＰＥＮＡＮＡxNsk203KnQ
80Please respect copyright.ＰＥＮＡＮＡcLzJxAPBmb
「欸欸欸先不要我腦袋已經快燒起來了啦！」80Please respect copyright.ＰＥＮＡＮＡmKkYYnPozi
80Please respect copyright.ＰＥＮＡＮＡllIYKAsG6W
她整個人癱倒在沙發上，拿抱枕壓著臉，一邊悶聲說：「為什麼這種東西你們都會……」80Please respect copyright.ＰＥＮＡＮＡpaGJ3sLVSI
80Please respect copyright.ＰＥＮＡＮＡ4QITYI8Zwd
「這上中學就有教了。」80Please respect copyright.ＰＥＮＡＮＡ8JH3QjNYDs
80Please respect copyright.ＰＥＮＡＮＡTfIMmZAtj2
「啊？」80Please respect copyright.ＰＥＮＡＮＡe7WqOxfVrI
80Please respect copyright.ＰＥＮＡＮＡjUfcJfOLMS
曹賢穎又翻到下一頁：「不然我們休息一下，等一下來看配方法解方程式。」80Please respect copyright.ＰＥＮＡＮＡ0YA8HJSpNT
80Please respect copyright.ＰＥＮＡＮＡAw3qJViV44
「配什麼……？那什麼……？」80Please respect copyright.ＰＥＮＡＮＡviEZTFwKEr
80Please respect copyright.ＰＥＮＡＮＡB2t7PR8Zvm
他沒說話，默默地在筆記上寫下了一道更難的題目。80Please respect copyright.ＰＥＮＡＮＡodcZ0uEdtQ
半小時後，卞芳華趴在桌上，看著一張又一張密密麻麻的算式，像是靈魂出竅一樣。80Please respect copyright.ＰＥＮＡＮＡqMUUSF9kgJ
「好了嗎？」曹賢穎耐心的看著她。80Please respect copyright.ＰＥＮＡＮＡyd3MkKD1iN
80Please respect copyright.ＰＥＮＡＮＡUHS06o34kP
「我真的要死了……」她吸了一口剛剛外送送的冰奶茶瞬間復活，「好啦，再來一題！」80Please respect copyright.ＰＥＮＡＮＡITgNcdPLzG
