「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。40Please respect copyright.ＰＥＮＡＮＡ9KuU1rz6p8
「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。40Please respect copyright.ＰＥＮＡＮＡbsWdCD7Uft
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。40Please respect copyright.ＰＥＮＡＮＡSnOzltTvSW
然後，她又慢慢不出現在學校了。40Please respect copyright.ＰＥＮＡＮＡJHmmNdoA61
直到，她父親回國。40Please respect copyright.ＰＥＮＡＮＡ6VzfeNWgUz
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。40Please respect copyright.ＰＥＮＡＮＡiX0w2JFVok
結果下一秒她看到門口的那張臉，魂差點飛出去。40Please respect copyright.ＰＥＮＡＮＡ9oDFSsmnb9
40Please respect copyright.ＰＥＮＡＮＡXg2gbpJQfi
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。40Please respect copyright.ＰＥＮＡＮＡwUPw2J39iR
40Please respect copyright.ＰＥＮＡＮＡb2jTAL3Xa3
「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？」40Please respect copyright.ＰＥＮＡＮＡeqMhNyWTkF
40Please respect copyright.ＰＥＮＡＮＡhOJqFBAUWG
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。40Please respect copyright.ＰＥＮＡＮＡ5XHouzTkgK
40Please respect copyright.ＰＥＮＡＮＡ2OJ6gc3sUt
「蛤？」那一聲像審判。40Please respect copyright.ＰＥＮＡＮＡCeaamg5Tkd
40Please respect copyright.ＰＥＮＡＮＡdDwDQSEGy3
「對不起對不起對不起！」她舉雙手投降。40Please respect copyright.ＰＥＮＡＮＡCfQ1hmCvOT
40Please respect copyright.ＰＥＮＡＮＡovxYKtyvM5
「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。40Please respect copyright.ＰＥＮＡＮＡZwfV1bioHX
於是，卞芳華又乖乖回去上課了。40Please respect copyright.ＰＥＮＡＮＡldh5lf8pbh
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。40Please respect copyright.ＰＥＮＡＮＡBauoHQGlCR
「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。40Please respect copyright.ＰＥＮＡＮＡu8SfqvdPwy
40Please respect copyright.ＰＥＮＡＮＡPozBQ8ZJ0j
「嗯，沒問題。」曹賢穎不多話地答應了。40Please respect copyright.ＰＥＮＡＮＡU6FwKgoYtg
於是曹賢穎開始了他的補課初體驗。40Please respect copyright.ＰＥＮＡＮＡ4mg3hlSOvF
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」40Please respect copyright.ＰＥＮＡＮＡalef4JoBj8
40Please respect copyright.ＰＥＮＡＮＡ2cd658aa0j
「嗯，妳好。」40Please respect copyright.ＰＥＮＡＮＡaMr3tObrKV
40Please respect copyright.ＰＥＮＡＮＡk40b4YsYrX
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。40Please respect copyright.ＰＥＮＡＮＡWd7VAKHJM2
40Please respect copyright.ＰＥＮＡＮＡ2nPizNJd0X
「我應該坐哪裡？」40Please respect copyright.ＰＥＮＡＮＡi3S3L3XuWQ
40Please respect copyright.ＰＥＮＡＮＡ6xNAp6VpcD
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。40Please respect copyright.ＰＥＮＡＮＡWZQh7DLtw1
40Please respect copyright.ＰＥＮＡＮＡWZ6dJAbcKE
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」40Please respect copyright.ＰＥＮＡＮＡZNUrnZ0MSi
40Please respect copyright.ＰＥＮＡＮＡMdz8GxdAly
曹賢穎坐在她旁邊，拿出自己的筆電。40Please respect copyright.ＰＥＮＡＮＡEQ7bXLC04m
「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？」40Please respect copyright.ＰＥＮＡＮＡhFCZhacfEY
「呃……我記得有聽過啦……」卞芳華一臉迷茫。40Please respect copyright.ＰＥＮＡＮＡI8fUqT31tl
40Please respect copyright.ＰＥＮＡＮＡGff2VApyQB
他舉起筆，寫下：40Please respect copyright.ＰＥＮＡＮＡ48JV4VggwJ
40Please respect copyright.ＰＥＮＡＮＡ22shDRQEsC
x² + 5x + 6 = 040Please respect copyright.ＰＥＮＡＮＡqrxSsCXa7v
「這題怎麼解？」他問。40Please respect copyright.ＰＥＮＡＮＡuFGICzedmo
40Please respect copyright.ＰＥＮＡＮＡZNFoctn1o2
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」40Please respect copyright.ＰＥＮＡＮＡeDyf2Kz8pc
40Please respect copyright.ＰＥＮＡＮＡmbKNIcBDqF
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」40Please respect copyright.ＰＥＮＡＮＡNXzbiTVkwm
40Please respect copyright.ＰＥＮＡＮＡnKHsKOKDw7
曹賢穎寫下：40Please respect copyright.ＰＥＮＡＮＡjzrhJsUnKK
40Please respect copyright.ＰＥＮＡＮＡKzHxfSGRDP
(x + 2)(x + 3) = 040Please respect copyright.ＰＥＮＡＮＡRya2AsBbSk
「所以解是？」40Please respect copyright.ＰＥＮＡＮＡCu091tmDXI
40Please respect copyright.ＰＥＮＡＮＡN8oBksYfaN
「x = -2，x = -3？」40Please respect copyright.ＰＥＮＡＮＡOUWTR1VoRl
40Please respect copyright.ＰＥＮＡＮＡoJjkMwxolo
「對，這題妳還可以。」40Please respect copyright.ＰＥＮＡＮＡsODDiibwJi
40Please respect copyright.ＰＥＮＡＮＡUpfhHcsCdx
「耶～」她開心地握拳。40Please respect copyright.ＰＥＮＡＮＡ2PsjT80BW5
40Please respect copyright.ＰＥＮＡＮＡo7gpWg4K74
「那這題呢？」他接著寫下：40Please respect copyright.ＰＥＮＡＮＡoaNfmji7Te
40Please respect copyright.ＰＥＮＡＮＡqKq5eri8zd
x² - 7x + 10 = 040Please respect copyright.ＰＥＮＡＮＡ2WkeLekHRa
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」40Please respect copyright.ＰＥＮＡＮＡL1g3BnKzQs
40Please respect copyright.ＰＥＮＡＮＡQBC6wwHL1R
「不對，5跟2乘起來是10，但加起來是7，不是負7。」40Please respect copyright.ＰＥＮＡＮＡLwYNoRKr51
40Please respect copyright.ＰＥＮＡＮＡ9TTYY4uKY8
「哦哦對齁……」40Please respect copyright.ＰＥＮＡＮＡali7zWZ6bW
40Please respect copyright.ＰＥＮＡＮＡrvs7shgY3o
「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。」40Please respect copyright.ＰＥＮＡＮＡ2zOSTbjZVC
40Please respect copyright.ＰＥＮＡＮＡJZvdnHIYn1
「……1跟10、2跟5……喔！是-2跟-5對吧！」40Please respect copyright.ＰＥＮＡＮＡBo8czrBhkE
40Please respect copyright.ＰＥＮＡＮＡbIGmCuq2in
「嗯，不錯，那妳寫出來看看。」40Please respect copyright.ＰＥＮＡＮＡUh3Sv2eGn9
40Please respect copyright.ＰＥＮＡＮＡeAgSggzB54
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。40Please respect copyright.ＰＥＮＡＮＡwpToXGSEXc
40Please respect copyright.ＰＥＮＡＮＡFv4d5v7vU0
「欸不對啊……我是不是少了什麼……」40Please respect copyright.ＰＥＮＡＮＡxuEftxjTQW
40Please respect copyright.ＰＥＮＡＮＡIkYUAJjA4Y
「沒有錯啊，妳做對了。」40Please respect copyright.ＰＥＮＡＮＡ3zWKo00sMz
40Please respect copyright.ＰＥＮＡＮＡMyl94KhP0P
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」40Please respect copyright.ＰＥＮＡＮＡrWSQ5vD6fp
40Please respect copyright.ＰＥＮＡＮＡffd66gf18p
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。」40Please respect copyright.ＰＥＮＡＮＡX0UX0UNm89
40Please respect copyright.ＰＥＮＡＮＡr9Ej3du2uR
「欸欸欸先不要我腦袋已經快燒起來了啦！」40Please respect copyright.ＰＥＮＡＮＡsyNPy3pIJF
40Please respect copyright.ＰＥＮＡＮＡMrDHhgwebn
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……」40Please respect copyright.ＰＥＮＡＮＡaKH8DqdlO0
40Please respect copyright.ＰＥＮＡＮＡelPzxWZbJE
「這上中學就有教了。」40Please respect copyright.ＰＥＮＡＮＡuv1KQnoRM5
40Please respect copyright.ＰＥＮＡＮＡWiaqSV6RHq
「啊？」40Please respect copyright.ＰＥＮＡＮＡEUAgbrEaWo
40Please respect copyright.ＰＥＮＡＮＡcSU0NgnFbV
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。」40Please respect copyright.ＰＥＮＡＮＡSlf29BnVb1
40Please respect copyright.ＰＥＮＡＮＡqDzO6DKMwF
「配什麼……？那什麼……？」40Please respect copyright.ＰＥＮＡＮＡSu1RhFeU4z
40Please respect copyright.ＰＥＮＡＮＡVyCcppDUuC
他沒說話，默默地在筆記上寫下了一道更難的題目。40Please respect copyright.ＰＥＮＡＮＡH1CNBn6ZTX
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。40Please respect copyright.ＰＥＮＡＮＡaLfHCsD9hZ
「好了嗎？」曹賢穎耐心的看著她。40Please respect copyright.ＰＥＮＡＮＡTadKxwshPe
40Please respect copyright.ＰＥＮＡＮＡFiKk6UWtFO
「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！」40Please respect copyright.ＰＥＮＡＮＡvIka9CDDfL
