「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。104Please respect copyright.ＰＥＮＡＮＡgryJMuLaQ4
「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。104Please respect copyright.ＰＥＮＡＮＡR3Uecmfjyb
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。104Please respect copyright.ＰＥＮＡＮＡrGIGmefrcU
然後，她又慢慢不出現在學校了。104Please respect copyright.ＰＥＮＡＮＡUTxOzPjj1m
直到，她父親回國。104Please respect copyright.ＰＥＮＡＮＡWiGXgHEu3p
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。104Please respect copyright.ＰＥＮＡＮＡnLkmxGO4Xz
結果下一秒她看到門口的那張臉，魂差點飛出去。104Please respect copyright.ＰＥＮＡＮＡl8fNTWDOCj
104Please respect copyright.ＰＥＮＡＮＡAZnju5E2V7
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。104Please respect copyright.ＰＥＮＡＮＡqL4lYc5y16
104Please respect copyright.ＰＥＮＡＮＡdzFGxSNtoW
「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？」104Please respect copyright.ＰＥＮＡＮＡ5qSD7Rv6Vi
104Please respect copyright.ＰＥＮＡＮＡrIFolJcZCk
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。104Please respect copyright.ＰＥＮＡＮＡhxY5DeZkWO
104Please respect copyright.ＰＥＮＡＮＡvJmZi7Twll
「蛤？」那一聲像審判。104Please respect copyright.ＰＥＮＡＮＡvGSxtNJ3bq
104Please respect copyright.ＰＥＮＡＮＡzIYvT3qq8e
「對不起對不起對不起！」她舉雙手投降。104Please respect copyright.ＰＥＮＡＮＡma3mt6JqqR
104Please respect copyright.ＰＥＮＡＮＡJUTOUS1oaU
「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。104Please respect copyright.ＰＥＮＡＮＡhnil9wW58D
於是，卞芳華又乖乖回去上課了。104Please respect copyright.ＰＥＮＡＮＡ7hOpQd8hWO
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。104Please respect copyright.ＰＥＮＡＮＡ1hn8mJdoWL
「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。104Please respect copyright.ＰＥＮＡＮＡa5Il1Unxun
104Please respect copyright.ＰＥＮＡＮＡb6DaEnwaxl
「嗯，沒問題。」曹賢穎不多話地答應了。104Please respect copyright.ＰＥＮＡＮＡ8IAts67aDC
於是曹賢穎開始了他的補課初體驗。104Please respect copyright.ＰＥＮＡＮＡXlDDt0ImdM
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」104Please respect copyright.ＰＥＮＡＮＡNtPpABNLw3
104Please respect copyright.ＰＥＮＡＮＡ77N5TwOHnY
「嗯，妳好。」104Please respect copyright.ＰＥＮＡＮＡNt1NVVycdI
104Please respect copyright.ＰＥＮＡＮＡh5aenVTSR3
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。104Please respect copyright.ＰＥＮＡＮＡse2dNuEzdA
104Please respect copyright.ＰＥＮＡＮＡCDjgL54qim
「我應該坐哪裡？」104Please respect copyright.ＰＥＮＡＮＡYooOJuOBJg
104Please respect copyright.ＰＥＮＡＮＡcJOfXdiMmL
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。104Please respect copyright.ＰＥＮＡＮＡrtOr3BEfPI
104Please respect copyright.ＰＥＮＡＮＡTwQ6eIDwgP
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」104Please respect copyright.ＰＥＮＡＮＡynMCBt3Z1x
104Please respect copyright.ＰＥＮＡＮＡV1CI9wjig8
曹賢穎坐在她旁邊，拿出自己的筆電。104Please respect copyright.ＰＥＮＡＮＡ3GyeQRRNVp
「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？」104Please respect copyright.ＰＥＮＡＮＡ0pzG07lOod
「呃……我記得有聽過啦……」卞芳華一臉迷茫。104Please respect copyright.ＰＥＮＡＮＡbYDVDriULV
104Please respect copyright.ＰＥＮＡＮＡJx0YrSCyfb
他舉起筆，寫下：104Please respect copyright.ＰＥＮＡＮＡhJ1oI0ZAaJ
104Please respect copyright.ＰＥＮＡＮＡcmQrUp6Ss8
x² + 5x + 6 = 0104Please respect copyright.ＰＥＮＡＮＡZWZ6c3zn79
「這題怎麼解？」他問。104Please respect copyright.ＰＥＮＡＮＡvMkA24twpu
104Please respect copyright.ＰＥＮＡＮＡrOG83LfCy8
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」104Please respect copyright.ＰＥＮＡＮＡeSMTKMoyKU
104Please respect copyright.ＰＥＮＡＮＡxX1mXzIvPu
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」104Please respect copyright.ＰＥＮＡＮＡOMsjNjcLf7
104Please respect copyright.ＰＥＮＡＮＡchFGdAKVL9
曹賢穎寫下：104Please respect copyright.ＰＥＮＡＮＡaO7k5mXw5I
104Please respect copyright.ＰＥＮＡＮＡ09dLGgQH3z
(x + 2)(x + 3) = 0104Please respect copyright.ＰＥＮＡＮＡU2jIx73HRO
「所以解是？」104Please respect copyright.ＰＥＮＡＮＡzIgDeD0UWH
104Please respect copyright.ＰＥＮＡＮＡBFXPSv7rA0
「x = -2，x = -3？」104Please respect copyright.ＰＥＮＡＮＡf48GdAk5Kw
104Please respect copyright.ＰＥＮＡＮＡSkyhuY6klD
「對，這題妳還可以。」104Please respect copyright.ＰＥＮＡＮＡjW856tPUil
104Please respect copyright.ＰＥＮＡＮＡaoUvv3tOQt
「耶～」她開心地握拳。104Please respect copyright.ＰＥＮＡＮＡRKOX7sx9t5
104Please respect copyright.ＰＥＮＡＮＡjuzNoY9DeC
「那這題呢？」他接著寫下：104Please respect copyright.ＰＥＮＡＮＡXohRdjlwRm
104Please respect copyright.ＰＥＮＡＮＡiNxrSmDCKV
x² - 7x + 10 = 0104Please respect copyright.ＰＥＮＡＮＡUJVI9Wl3ud
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」104Please respect copyright.ＰＥＮＡＮＡpikyJQMAcB
104Please respect copyright.ＰＥＮＡＮＡxZdXi8jp0u
「不對，5跟2乘起來是10，但加起來是7，不是負7。」104Please respect copyright.ＰＥＮＡＮＡu6G24uouZW
104Please respect copyright.ＰＥＮＡＮＡ9BT5g8H9d5
「哦哦對齁……」104Please respect copyright.ＰＥＮＡＮＡObzxloe6GP
104Please respect copyright.ＰＥＮＡＮＡDkqfTj3UYk
「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。」104Please respect copyright.ＰＥＮＡＮＡG3KTjppI7S
104Please respect copyright.ＰＥＮＡＮＡHIdaOUYRnu
「……1跟10、2跟5……喔！是-2跟-5對吧！」104Please respect copyright.ＰＥＮＡＮＡJMYG8pW4Rl
104Please respect copyright.ＰＥＮＡＮＡHUsG9kaPtt
「嗯，不錯，那妳寫出來看看。」104Please respect copyright.ＰＥＮＡＮＡV8k3KjI1Wk
104Please respect copyright.ＰＥＮＡＮＡ0eEisbthnH
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。104Please respect copyright.ＰＥＮＡＮＡ6tBezTxGmz
104Please respect copyright.ＰＥＮＡＮＡvCfJW9Quxd
「欸不對啊……我是不是少了什麼……」104Please respect copyright.ＰＥＮＡＮＡhCZkUuBN7n
104Please respect copyright.ＰＥＮＡＮＡ9ceOFH2pg2
「沒有錯啊，妳做對了。」104Please respect copyright.ＰＥＮＡＮＡnfcIZsESAs
104Please respect copyright.ＰＥＮＡＮＡEY6gqZV7TK
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」104Please respect copyright.ＰＥＮＡＮＡUTqkzjrzVP
104Please respect copyright.ＰＥＮＡＮＡq8xGgCOSVe
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。」104Please respect copyright.ＰＥＮＡＮＡoQbazgVB8T
104Please respect copyright.ＰＥＮＡＮＡK1tderVWIA
「欸欸欸先不要我腦袋已經快燒起來了啦！」104Please respect copyright.ＰＥＮＡＮＡKjhyoZxg4j
104Please respect copyright.ＰＥＮＡＮＡUzqWh1npnP
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……」104Please respect copyright.ＰＥＮＡＮＡ8MPhQaRapy
104Please respect copyright.ＰＥＮＡＮＡp1nFqvc7yP
「這上中學就有教了。」104Please respect copyright.ＰＥＮＡＮＡQPn2TjacxG
104Please respect copyright.ＰＥＮＡＮＡjZClaGMgG1
「啊？」104Please respect copyright.ＰＥＮＡＮＡG66Ja8mKid
104Please respect copyright.ＰＥＮＡＮＡmcn6UxRzDi
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。」104Please respect copyright.ＰＥＮＡＮＡrRkH4Wrlkh
104Please respect copyright.ＰＥＮＡＮＡmTaQ9S4Bkp
「配什麼……？那什麼……？」104Please respect copyright.ＰＥＮＡＮＡr57ZbMNI2M
104Please respect copyright.ＰＥＮＡＮＡC3wvSNoSGD
他沒說話，默默地在筆記上寫下了一道更難的題目。104Please respect copyright.ＰＥＮＡＮＡHiG3uXWWLG
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。104Please respect copyright.ＰＥＮＡＮＡICQDHGElz6
「好了嗎？」曹賢穎耐心的看著她。104Please respect copyright.ＰＥＮＡＮＡlCfvTtyQRk
104Please respect copyright.ＰＥＮＡＮＡpMqActZGdl
「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！」104Please respect copyright.ＰＥＮＡＮＡ2yIQPw2aKh
