「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。67Please respect copyright.ＰＥＮＡＮＡ9MFthIc91W
「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。67Please respect copyright.ＰＥＮＡＮＡQU6luRtpCQ
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。67Please respect copyright.ＰＥＮＡＮＡLRmeEtpSWU
然後，她又慢慢不出現在學校了。67Please respect copyright.ＰＥＮＡＮＡvfq9C56BTO
直到，她父親回國。67Please respect copyright.ＰＥＮＡＮＡqErfu4PFqs
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。67Please respect copyright.ＰＥＮＡＮＡkxlTJ2POcz
結果下一秒她看到門口的那張臉，魂差點飛出去。67Please respect copyright.ＰＥＮＡＮＡAn2fNTyD8K
67Please respect copyright.ＰＥＮＡＮＡm5mvVP5w4k
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。67Please respect copyright.ＰＥＮＡＮＡeYgvVPCAqW
67Please respect copyright.ＰＥＮＡＮＡXwwMmivAKR
「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？」67Please respect copyright.ＰＥＮＡＮＡK250zuDAnO
67Please respect copyright.ＰＥＮＡＮＡHbVTqugtmE
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。67Please respect copyright.ＰＥＮＡＮＡynSwtN4Qay
67Please respect copyright.ＰＥＮＡＮＡdQYuGELUCO
「蛤？」那一聲像審判。67Please respect copyright.ＰＥＮＡＮＡ710QjS1YcN
67Please respect copyright.ＰＥＮＡＮＡjjeBgbaI8c
「對不起對不起對不起！」她舉雙手投降。67Please respect copyright.ＰＥＮＡＮＡUCH36QHdvt
67Please respect copyright.ＰＥＮＡＮＡiaTkC9Y7V2
「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。67Please respect copyright.ＰＥＮＡＮＡ4XshMnn55u
於是，卞芳華又乖乖回去上課了。67Please respect copyright.ＰＥＮＡＮＡngZfBF7sbl
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。67Please respect copyright.ＰＥＮＡＮＡWLttEwz2Bg
「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。67Please respect copyright.ＰＥＮＡＮＡvzkiN0xj4S
67Please respect copyright.ＰＥＮＡＮＡIr3LDXfQXi
「嗯，沒問題。」曹賢穎不多話地答應了。67Please respect copyright.ＰＥＮＡＮＡyWldQiy3s0
於是曹賢穎開始了他的補課初體驗。67Please respect copyright.ＰＥＮＡＮＡm2LYHgiqNP
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」67Please respect copyright.ＰＥＮＡＮＡfrrNXY5sgX
67Please respect copyright.ＰＥＮＡＮＡmac60asngt
「嗯，妳好。」67Please respect copyright.ＰＥＮＡＮＡAd3H0dgdwB
67Please respect copyright.ＰＥＮＡＮＡDcLXbX4LbE
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。67Please respect copyright.ＰＥＮＡＮＡFmd886zaJv
67Please respect copyright.ＰＥＮＡＮＡrCdZgAKTSp
「我應該坐哪裡？」67Please respect copyright.ＰＥＮＡＮＡuzpwrtGzmE
67Please respect copyright.ＰＥＮＡＮＡUPKk9v55ov
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。67Please respect copyright.ＰＥＮＡＮＡGn1Nl7PM4a
67Please respect copyright.ＰＥＮＡＮＡdWKGXfWPnd
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」67Please respect copyright.ＰＥＮＡＮＡfzWY2cULiT
67Please respect copyright.ＰＥＮＡＮＡoNEQYGIXtp
曹賢穎坐在她旁邊，拿出自己的筆電。67Please respect copyright.ＰＥＮＡＮＡKWWX2WrzXC
「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？」67Please respect copyright.ＰＥＮＡＮＡF2k5LWswPV
「呃……我記得有聽過啦……」卞芳華一臉迷茫。67Please respect copyright.ＰＥＮＡＮＡ2cTpxNuAPy
67Please respect copyright.ＰＥＮＡＮＡRgcexeTHtg
他舉起筆，寫下：67Please respect copyright.ＰＥＮＡＮＡzC6GVK4zuz
67Please respect copyright.ＰＥＮＡＮＡx272uKxUNh
x² + 5x + 6 = 067Please respect copyright.ＰＥＮＡＮＡYkYmZ2Syss
「這題怎麼解？」他問。67Please respect copyright.ＰＥＮＡＮＡhdoZZecizC
67Please respect copyright.ＰＥＮＡＮＡATwUKgh5ZP
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」67Please respect copyright.ＰＥＮＡＮＡoKr3tZFxI5
67Please respect copyright.ＰＥＮＡＮＡDEZQ6f8ASZ
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」67Please respect copyright.ＰＥＮＡＮＡ1LV77O8rBC
67Please respect copyright.ＰＥＮＡＮＡH3od0Pf71a
曹賢穎寫下：67Please respect copyright.ＰＥＮＡＮＡEx9R4RXdL4
67Please respect copyright.ＰＥＮＡＮＡsq9lZxe4WU
(x + 2)(x + 3) = 067Please respect copyright.ＰＥＮＡＮＡhUZH8Rs4CU
「所以解是？」67Please respect copyright.ＰＥＮＡＮＡEjXoZaZj6m
67Please respect copyright.ＰＥＮＡＮＡky0zpEMAkt
「x = -2，x = -3？」67Please respect copyright.ＰＥＮＡＮＡU5G1x75fft
67Please respect copyright.ＰＥＮＡＮＡvbASJGTcQF
「對，這題妳還可以。」67Please respect copyright.ＰＥＮＡＮＡPH6sSXHeYE
67Please respect copyright.ＰＥＮＡＮＡzAMzZK0bH7
「耶～」她開心地握拳。67Please respect copyright.ＰＥＮＡＮＡsv7pmSaqVS
67Please respect copyright.ＰＥＮＡＮＡcmLRcUaXSM
「那這題呢？」他接著寫下：67Please respect copyright.ＰＥＮＡＮＡSMjsifiQRS
67Please respect copyright.ＰＥＮＡＮＡq5ji5ezbJK
x² - 7x + 10 = 067Please respect copyright.ＰＥＮＡＮＡwlqrrJvBmi
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」67Please respect copyright.ＰＥＮＡＮＡEO6Zp4hlpK
67Please respect copyright.ＰＥＮＡＮＡQNEP7LeVXX
「不對，5跟2乘起來是10，但加起來是7，不是負7。」67Please respect copyright.ＰＥＮＡＮＡpYVd9TWett
67Please respect copyright.ＰＥＮＡＮＡDmChFpoDDX
「哦哦對齁……」67Please respect copyright.ＰＥＮＡＮＡY98b8kjqLq
67Please respect copyright.ＰＥＮＡＮＡCAZ7S8ipPs
「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。」67Please respect copyright.ＰＥＮＡＮＡ6RiB1zbOqb
67Please respect copyright.ＰＥＮＡＮＡB2oWvTthFO
「……1跟10、2跟5……喔！是-2跟-5對吧！」67Please respect copyright.ＰＥＮＡＮＡ56goU8Ukwj
67Please respect copyright.ＰＥＮＡＮＡCoJhaAKdyU
「嗯，不錯，那妳寫出來看看。」67Please respect copyright.ＰＥＮＡＮＡ1K8bkB6TOD
67Please respect copyright.ＰＥＮＡＮＡHCZPXnpmmh
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。67Please respect copyright.ＰＥＮＡＮＡ6XthCFvd4X
67Please respect copyright.ＰＥＮＡＮＡkVwi29fjmo
「欸不對啊……我是不是少了什麼……」67Please respect copyright.ＰＥＮＡＮＡW7vdQGx88I
67Please respect copyright.ＰＥＮＡＮＡ1H8tLHr7jQ
「沒有錯啊，妳做對了。」67Please respect copyright.ＰＥＮＡＮＡvQFl9eSjDS
67Please respect copyright.ＰＥＮＡＮＡEA5o1XTEB7
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」67Please respect copyright.ＰＥＮＡＮＡaYvojEc1VF
67Please respect copyright.ＰＥＮＡＮＡuZGEKv0b2l
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。」67Please respect copyright.ＰＥＮＡＮＡH9aBNPjGlu
67Please respect copyright.ＰＥＮＡＮＡUJU206nIVR
「欸欸欸先不要我腦袋已經快燒起來了啦！」67Please respect copyright.ＰＥＮＡＮＡR90DJ4wALY
67Please respect copyright.ＰＥＮＡＮＡibO1hdwUUX
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……」67Please respect copyright.ＰＥＮＡＮＡVg2OUgqF2j
67Please respect copyright.ＰＥＮＡＮＡupU2HbymQs
「這上中學就有教了。」67Please respect copyright.ＰＥＮＡＮＡTpZxpyQWoy
67Please respect copyright.ＰＥＮＡＮＡVXJCPeHiMc
「啊？」67Please respect copyright.ＰＥＮＡＮＡFt4WFpbsvB
67Please respect copyright.ＰＥＮＡＮＡLQi3HAS20Y
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。」67Please respect copyright.ＰＥＮＡＮＡKFa8RBOAEm
67Please respect copyright.ＰＥＮＡＮＡFc3zjkrsIv
「配什麼……？那什麼……？」67Please respect copyright.ＰＥＮＡＮＡkGw41bdgpu
67Please respect copyright.ＰＥＮＡＮＡIbKXsAAS8X
他沒說話，默默地在筆記上寫下了一道更難的題目。67Please respect copyright.ＰＥＮＡＮＡVEXFUHGKMI
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。67Please respect copyright.ＰＥＮＡＮＡRngvx7qTFq
「好了嗎？」曹賢穎耐心的看著她。67Please respect copyright.ＰＥＮＡＮＡZZ5cETnIDM
67Please respect copyright.ＰＥＮＡＮＡWd2jqb3P7J
「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！」67Please respect copyright.ＰＥＮＡＮＡ0MWXm6iGOK
