「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。39Please respect copyright.ＰＥＮＡＮＡjVzUBuvgri
「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。39Please respect copyright.ＰＥＮＡＮＡxEl6nzvV9U
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。39Please respect copyright.ＰＥＮＡＮＡYHh6Gk2HKa
然後，她又慢慢不出現在學校了。39Please respect copyright.ＰＥＮＡＮＡG1gaxqYXbK
直到，她父親回國。39Please respect copyright.ＰＥＮＡＮＡDTBWabv5D2
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。39Please respect copyright.ＰＥＮＡＮＡo6WjsmkR5l
結果下一秒她看到門口的那張臉，魂差點飛出去。39Please respect copyright.ＰＥＮＡＮＡGB2l0HUAr0
39Please respect copyright.ＰＥＮＡＮＡ6PCj0CJv6Y
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。39Please respect copyright.ＰＥＮＡＮＡWgH2I7W3CI
39Please respect copyright.ＰＥＮＡＮＡeWXM1PtQD4
「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？」39Please respect copyright.ＰＥＮＡＮＡ5vasXnTjLx
39Please respect copyright.ＰＥＮＡＮＡ2dj2LKZ04D
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。39Please respect copyright.ＰＥＮＡＮＡPbM96iW0YM
39Please respect copyright.ＰＥＮＡＮＡctsSmVHIpX
「蛤？」那一聲像審判。39Please respect copyright.ＰＥＮＡＮＡb40avSyLmz
39Please respect copyright.ＰＥＮＡＮＡbaowPYLTP1
「對不起對不起對不起！」她舉雙手投降。39Please respect copyright.ＰＥＮＡＮＡMx86zigCSJ
39Please respect copyright.ＰＥＮＡＮＡOEHjvxOAB8
「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。39Please respect copyright.ＰＥＮＡＮＡmGfEB0tuNE
於是，卞芳華又乖乖回去上課了。39Please respect copyright.ＰＥＮＡＮＡRl0Vdk144D
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。39Please respect copyright.ＰＥＮＡＮＡTMaJ8CwB9Q
「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。39Please respect copyright.ＰＥＮＡＮＡJLVHj6lqEB
39Please respect copyright.ＰＥＮＡＮＡyPzcE4E2el
「嗯，沒問題。」曹賢穎不多話地答應了。39Please respect copyright.ＰＥＮＡＮＡyeyP1TWYlv
於是曹賢穎開始了他的補課初體驗。39Please respect copyright.ＰＥＮＡＮＡgbhUlrhSDn
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」39Please respect copyright.ＰＥＮＡＮＡjhQwKH897X
39Please respect copyright.ＰＥＮＡＮＡMgK1G6uRmk
「嗯，妳好。」39Please respect copyright.ＰＥＮＡＮＡ2USb7MnM4V
39Please respect copyright.ＰＥＮＡＮＡGPIhZpywq1
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。39Please respect copyright.ＰＥＮＡＮＡmzhfLZZjIT
39Please respect copyright.ＰＥＮＡＮＡbdjlWtTsRw
「我應該坐哪裡？」39Please respect copyright.ＰＥＮＡＮＡ5IDRNuRw5a
39Please respect copyright.ＰＥＮＡＮＡWBLPZZlOlE
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。39Please respect copyright.ＰＥＮＡＮＡxhFsgVahTF
39Please respect copyright.ＰＥＮＡＮＡwIUjhGC3Qw
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」39Please respect copyright.ＰＥＮＡＮＡ2IatyugUiX
39Please respect copyright.ＰＥＮＡＮＡe12IrZsqoR
曹賢穎坐在她旁邊，拿出自己的筆電。39Please respect copyright.ＰＥＮＡＮＡKZj1xl84yH
「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？」39Please respect copyright.ＰＥＮＡＮＡdmp8XB52VP
「呃……我記得有聽過啦……」卞芳華一臉迷茫。39Please respect copyright.ＰＥＮＡＮＡxbIUgQcZZU
39Please respect copyright.ＰＥＮＡＮＡRZAx2OFvKF
他舉起筆，寫下：39Please respect copyright.ＰＥＮＡＮＡq6VlmtKllh
39Please respect copyright.ＰＥＮＡＮＡHPRTTmISAL
x² + 5x + 6 = 039Please respect copyright.ＰＥＮＡＮＡ9KrFA7vrl2
「這題怎麼解？」他問。39Please respect copyright.ＰＥＮＡＮＡ9DwOL4zlZS
39Please respect copyright.ＰＥＮＡＮＡYLMiCZQRZM
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」39Please respect copyright.ＰＥＮＡＮＡotSugsJRmw
39Please respect copyright.ＰＥＮＡＮＡj6Cz1VHk3q
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」39Please respect copyright.ＰＥＮＡＮＡMNQuxcRuDI
39Please respect copyright.ＰＥＮＡＮＡvdH1NAZWSl
曹賢穎寫下：39Please respect copyright.ＰＥＮＡＮＡVqMUeQqdKf
39Please respect copyright.ＰＥＮＡＮＡCsaEELvARN
(x + 2)(x + 3) = 039Please respect copyright.ＰＥＮＡＮＡnVatDVULS8
「所以解是？」39Please respect copyright.ＰＥＮＡＮＡRrYTe5ueYA
39Please respect copyright.ＰＥＮＡＮＡ8RHddnYseU
「x = -2，x = -3？」39Please respect copyright.ＰＥＮＡＮＡw2kSKhPLv1
39Please respect copyright.ＰＥＮＡＮＡ3XQbPSQuNX
「對，這題妳還可以。」39Please respect copyright.ＰＥＮＡＮＡZAXLS7SEy2
39Please respect copyright.ＰＥＮＡＮＡSUNRzkOCbw
「耶～」她開心地握拳。39Please respect copyright.ＰＥＮＡＮＡwZcpt6Bl8C
39Please respect copyright.ＰＥＮＡＮＡRPJcgiB9EV
「那這題呢？」他接著寫下：39Please respect copyright.ＰＥＮＡＮＡzZs9blJAKZ
39Please respect copyright.ＰＥＮＡＮＡFThHSZl3gR
x² - 7x + 10 = 039Please respect copyright.ＰＥＮＡＮＡ063N4KKxCb
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」39Please respect copyright.ＰＥＮＡＮＡhUeMtcsUQM
39Please respect copyright.ＰＥＮＡＮＡ5jSHtgyjDC
「不對，5跟2乘起來是10，但加起來是7，不是負7。」39Please respect copyright.ＰＥＮＡＮＡH0rGAAUDkH
39Please respect copyright.ＰＥＮＡＮＡctKVIxIGvW
「哦哦對齁……」39Please respect copyright.ＰＥＮＡＮＡXBPVXpoaVQ
39Please respect copyright.ＰＥＮＡＮＡ1LmT6GOJZM
「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。」39Please respect copyright.ＰＥＮＡＮＡcf4JhArpiG
39Please respect copyright.ＰＥＮＡＮＡMGUuyM6n8T
「……1跟10、2跟5……喔！是-2跟-5對吧！」39Please respect copyright.ＰＥＮＡＮＡinQTHJACBo
39Please respect copyright.ＰＥＮＡＮＡ7wu9YBZhWy
「嗯，不錯，那妳寫出來看看。」39Please respect copyright.ＰＥＮＡＮＡ0qOd4lcguo
39Please respect copyright.ＰＥＮＡＮＡRxeqDPogVZ
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。39Please respect copyright.ＰＥＮＡＮＡL57zW2vR4E
39Please respect copyright.ＰＥＮＡＮＡ3FNVB3sZBd
「欸不對啊……我是不是少了什麼……」39Please respect copyright.ＰＥＮＡＮＡaTqqc6jIsN
39Please respect copyright.ＰＥＮＡＮＡNLesbLW4SS
「沒有錯啊，妳做對了。」39Please respect copyright.ＰＥＮＡＮＡvHa4YqYyoV
39Please respect copyright.ＰＥＮＡＮＡqXvnvvLmCA
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」39Please respect copyright.ＰＥＮＡＮＡrApSndreHD
39Please respect copyright.ＰＥＮＡＮＡ4525E38kzI
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。」39Please respect copyright.ＰＥＮＡＮＡ8LcJNPo90x
39Please respect copyright.ＰＥＮＡＮＡFB2Raxyecn
「欸欸欸先不要我腦袋已經快燒起來了啦！」39Please respect copyright.ＰＥＮＡＮＡa88t5lVOrU
39Please respect copyright.ＰＥＮＡＮＡTOYfopneUZ
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……」39Please respect copyright.ＰＥＮＡＮＡ59MwI2GCwq
39Please respect copyright.ＰＥＮＡＮＡ5pwCVMItKN
「這上中學就有教了。」39Please respect copyright.ＰＥＮＡＮＡP1yhm7qczB
39Please respect copyright.ＰＥＮＡＮＡeemzxEqqJm
「啊？」39Please respect copyright.ＰＥＮＡＮＡt1wHVuQlJ5
39Please respect copyright.ＰＥＮＡＮＡh2Stfg8Ofa
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。」39Please respect copyright.ＰＥＮＡＮＡnPRxXCQBjz
39Please respect copyright.ＰＥＮＡＮＡiTS0BQzZ2L
「配什麼……？那什麼……？」39Please respect copyright.ＰＥＮＡＮＡTehWthxS54
39Please respect copyright.ＰＥＮＡＮＡ0cLbJCLPap
他沒說話，默默地在筆記上寫下了一道更難的題目。39Please respect copyright.ＰＥＮＡＮＡteZwIfWUIl
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。39Please respect copyright.ＰＥＮＡＮＡ4dLxgdz6nT
「好了嗎？」曹賢穎耐心的看著她。39Please respect copyright.ＰＥＮＡＮＡRTmRgrQesI
39Please respect copyright.ＰＥＮＡＮＡVw9UdCSsv2
「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！」39Please respect copyright.ＰＥＮＡＮＡUKoX3T3tyX
