「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。81Please respect copyright.ＰＥＮＡＮＡDZlDGczSwk
「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。81Please respect copyright.ＰＥＮＡＮＡqTdI9znVy1
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。81Please respect copyright.ＰＥＮＡＮＡqzZlm7y723
然後，她又慢慢不出現在學校了。81Please respect copyright.ＰＥＮＡＮＡBbs1JpgQyk
直到，她父親回國。81Please respect copyright.ＰＥＮＡＮＡo1lxrxChxM
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。81Please respect copyright.ＰＥＮＡＮＡzsVWHOAGlv
結果下一秒她看到門口的那張臉，魂差點飛出去。81Please respect copyright.ＰＥＮＡＮＡnDR3x3iP0k
81Please respect copyright.ＰＥＮＡＮＡ4pj9pHXHWR
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。81Please respect copyright.ＰＥＮＡＮＡeey1i02ugr
81Please respect copyright.ＰＥＮＡＮＡBOukf7sUie
「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？」81Please respect copyright.ＰＥＮＡＮＡr9qPWdQ9m0
81Please respect copyright.ＰＥＮＡＮＡ4kqG739ocV
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。81Please respect copyright.ＰＥＮＡＮＡT52YmPbsqy
81Please respect copyright.ＰＥＮＡＮＡMZ4o9i1LeB
「蛤？」那一聲像審判。81Please respect copyright.ＰＥＮＡＮＡxZsM2ffu9B
81Please respect copyright.ＰＥＮＡＮＡgkVbvicUfD
「對不起對不起對不起！」她舉雙手投降。81Please respect copyright.ＰＥＮＡＮＡyJJzm6uWnh
81Please respect copyright.ＰＥＮＡＮＡM7aKAsMwgU
「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。81Please respect copyright.ＰＥＮＡＮＡ5biPv1j3Ks
於是，卞芳華又乖乖回去上課了。81Please respect copyright.ＰＥＮＡＮＡeVG9M5ynNN
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。81Please respect copyright.ＰＥＮＡＮＡ0YVWthFPab
「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。81Please respect copyright.ＰＥＮＡＮＡNS3VHGgGyY
81Please respect copyright.ＰＥＮＡＮＡtfOSeJQ1m0
「嗯，沒問題。」曹賢穎不多話地答應了。81Please respect copyright.ＰＥＮＡＮＡX0YCasamnY
於是曹賢穎開始了他的補課初體驗。81Please respect copyright.ＰＥＮＡＮＡWUOZ6B9vtQ
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」81Please respect copyright.ＰＥＮＡＮＡ5AeJHZBHN8
81Please respect copyright.ＰＥＮＡＮＡQQdxajIqrJ
「嗯，妳好。」81Please respect copyright.ＰＥＮＡＮＡAsufI0z7vf
81Please respect copyright.ＰＥＮＡＮＡrc71twmKlg
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。81Please respect copyright.ＰＥＮＡＮＡRGNwqENLxa
81Please respect copyright.ＰＥＮＡＮＡW2XQroTSZP
「我應該坐哪裡？」81Please respect copyright.ＰＥＮＡＮＡAybHD3Q0Xl
81Please respect copyright.ＰＥＮＡＮＡ3K26eRoHVI
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。81Please respect copyright.ＰＥＮＡＮＡgW5IqVswej
81Please respect copyright.ＰＥＮＡＮＡpmTTsTnFli
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」81Please respect copyright.ＰＥＮＡＮＡT950so9YsW
81Please respect copyright.ＰＥＮＡＮＡfTdJ52srwe
曹賢穎坐在她旁邊，拿出自己的筆電。81Please respect copyright.ＰＥＮＡＮＡfP8leoMvdv
「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？」81Please respect copyright.ＰＥＮＡＮＡsygB80zkPc
「呃……我記得有聽過啦……」卞芳華一臉迷茫。81Please respect copyright.ＰＥＮＡＮＡc3okuMPpI6
81Please respect copyright.ＰＥＮＡＮＡqj5ls4Fo0n
他舉起筆，寫下：81Please respect copyright.ＰＥＮＡＮＡkkjolV3qRj
81Please respect copyright.ＰＥＮＡＮＡAplAIwYbxG
x² + 5x + 6 = 081Please respect copyright.ＰＥＮＡＮＡUJ87A87Jgq
「這題怎麼解？」他問。81Please respect copyright.ＰＥＮＡＮＡG9ypGUXv4L
81Please respect copyright.ＰＥＮＡＮＡX44kVp1GZj
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」81Please respect copyright.ＰＥＮＡＮＡDiUauoinBa
81Please respect copyright.ＰＥＮＡＮＡgRbsTZIXQ5
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」81Please respect copyright.ＰＥＮＡＮＡY1W1e7UGPv
81Please respect copyright.ＰＥＮＡＮＡG9ApTcHKbs
曹賢穎寫下：81Please respect copyright.ＰＥＮＡＮＡhBerOKoyex
81Please respect copyright.ＰＥＮＡＮＡBOJzGhVQ1K
(x + 2)(x + 3) = 081Please respect copyright.ＰＥＮＡＮＡq4EmgLSFtV
「所以解是？」81Please respect copyright.ＰＥＮＡＮＡRA55foA3iX
81Please respect copyright.ＰＥＮＡＮＡ7Ke2YMEB07
「x = -2，x = -3？」81Please respect copyright.ＰＥＮＡＮＡmbKmwy4BV2
81Please respect copyright.ＰＥＮＡＮＡn8KdSxwpwN
「對，這題妳還可以。」81Please respect copyright.ＰＥＮＡＮＡzBUMCaoswp
81Please respect copyright.ＰＥＮＡＮＡYc7hDZchSQ
「耶～」她開心地握拳。81Please respect copyright.ＰＥＮＡＮＡXdEoEJr7Dw
81Please respect copyright.ＰＥＮＡＮＡFcaLn7hyiJ
「那這題呢？」他接著寫下：81Please respect copyright.ＰＥＮＡＮＡcpP1kz4Sm1
81Please respect copyright.ＰＥＮＡＮＡUxGKEQdxbi
x² - 7x + 10 = 081Please respect copyright.ＰＥＮＡＮＡROjVK1r1Ro
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」81Please respect copyright.ＰＥＮＡＮＡKesYiS1dRS
81Please respect copyright.ＰＥＮＡＮＡ5Ap0OxawUT
「不對，5跟2乘起來是10，但加起來是7，不是負7。」81Please respect copyright.ＰＥＮＡＮＡ35tmsAaCgP
81Please respect copyright.ＰＥＮＡＮＡpc3FtucvAe
「哦哦對齁……」81Please respect copyright.ＰＥＮＡＮＡI0gBipczKm
81Please respect copyright.ＰＥＮＡＮＡrhHuDInxek
「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。」81Please respect copyright.ＰＥＮＡＮＡmbKXqdcYrF
81Please respect copyright.ＰＥＮＡＮＡ7UMkRrHGdi
「……1跟10、2跟5……喔！是-2跟-5對吧！」81Please respect copyright.ＰＥＮＡＮＡEIWiNs6PkV
81Please respect copyright.ＰＥＮＡＮＡA9U2MKLttp
「嗯，不錯，那妳寫出來看看。」81Please respect copyright.ＰＥＮＡＮＡIAumu6G8BA
81Please respect copyright.ＰＥＮＡＮＡ7JXRSEJUUQ
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。81Please respect copyright.ＰＥＮＡＮＡ35trNTITew
81Please respect copyright.ＰＥＮＡＮＡOXz7HX2rnd
「欸不對啊……我是不是少了什麼……」81Please respect copyright.ＰＥＮＡＮＡnj9yGxkCUG
81Please respect copyright.ＰＥＮＡＮＡCSLpHFSTy1
「沒有錯啊，妳做對了。」81Please respect copyright.ＰＥＮＡＮＡnPhCaQpmW9
81Please respect copyright.ＰＥＮＡＮＡ2XDMYcAFdb
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」81Please respect copyright.ＰＥＮＡＮＡhIdtSUU8W0
81Please respect copyright.ＰＥＮＡＮＡ2ynInNM4Nt
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。」81Please respect copyright.ＰＥＮＡＮＡpd4Lute3X4
81Please respect copyright.ＰＥＮＡＮＡpl5Y2B3vxs
「欸欸欸先不要我腦袋已經快燒起來了啦！」81Please respect copyright.ＰＥＮＡＮＡ57rzemv3Gh
81Please respect copyright.ＰＥＮＡＮＡ5bLdkHXVKd
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……」81Please respect copyright.ＰＥＮＡＮＡUJ1KmeBYr1
81Please respect copyright.ＰＥＮＡＮＡgni4MHlLRu
「這上中學就有教了。」81Please respect copyright.ＰＥＮＡＮＡHoie8D3Mee
81Please respect copyright.ＰＥＮＡＮＡQQFS9ntr8J
「啊？」81Please respect copyright.ＰＥＮＡＮＡovPjod1BW9
81Please respect copyright.ＰＥＮＡＮＡoS6DR1f1HV
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。」81Please respect copyright.ＰＥＮＡＮＡhFnam9W9ni
81Please respect copyright.ＰＥＮＡＮＡyuTRRPzl5E
「配什麼……？那什麼……？」81Please respect copyright.ＰＥＮＡＮＡqMk3kfiwOU
81Please respect copyright.ＰＥＮＡＮＡyI9DYPv2fy
他沒說話，默默地在筆記上寫下了一道更難的題目。81Please respect copyright.ＰＥＮＡＮＡ2aFyBuv3us
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。81Please respect copyright.ＰＥＮＡＮＡnMi5imJi0P
「好了嗎？」曹賢穎耐心的看著她。81Please respect copyright.ＰＥＮＡＮＡcjrHLT7pWQ
81Please respect copyright.ＰＥＮＡＮＡuIFLHEUoev
「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！」81Please respect copyright.ＰＥＮＡＮＡaHK4S0g1zw
