「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。45Please respect copyright.ＰＥＮＡＮＡrIlyPgEUpn
「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。45Please respect copyright.ＰＥＮＡＮＡlVeFMHeDy1
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。45Please respect copyright.ＰＥＮＡＮＡOGdAD6yapq
然後，她又慢慢不出現在學校了。45Please respect copyright.ＰＥＮＡＮＡdHAdu6r1Vr
直到，她父親回國。45Please respect copyright.ＰＥＮＡＮＡ3pItTTVO55
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。45Please respect copyright.ＰＥＮＡＮＡbfrJOu0LaZ
結果下一秒她看到門口的那張臉，魂差點飛出去。45Please respect copyright.ＰＥＮＡＮＡQUFe6yORme
45Please respect copyright.ＰＥＮＡＮＡhQ8FbAmPgb
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。45Please respect copyright.ＰＥＮＡＮＡG7Fyx5hm5W
45Please respect copyright.ＰＥＮＡＮＡ85J2V80FFi
「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？」45Please respect copyright.ＰＥＮＡＮＡZJf8aBH5DG
45Please respect copyright.ＰＥＮＡＮＡE1jiw22e85
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。45Please respect copyright.ＰＥＮＡＮＡ3qGqEpek5c
45Please respect copyright.ＰＥＮＡＮＡOrZcmHBgDH
「蛤？」那一聲像審判。45Please respect copyright.ＰＥＮＡＮＡiwmgqrTqGw
45Please respect copyright.ＰＥＮＡＮＡ9n3Mh7iNkv
「對不起對不起對不起！」她舉雙手投降。45Please respect copyright.ＰＥＮＡＮＡjO3Cwo9NEx
45Please respect copyright.ＰＥＮＡＮＡJWK9YCRZh9
「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。45Please respect copyright.ＰＥＮＡＮＡNeueIxdcFc
於是，卞芳華又乖乖回去上課了。45Please respect copyright.ＰＥＮＡＮＡsfuoaRtNBx
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。45Please respect copyright.ＰＥＮＡＮＡEbpKe1fCPj
「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。45Please respect copyright.ＰＥＮＡＮＡO424mMWuMF
45Please respect copyright.ＰＥＮＡＮＡOcYaO5kGKN
「嗯，沒問題。」曹賢穎不多話地答應了。45Please respect copyright.ＰＥＮＡＮＡV7KEe1qNDq
於是曹賢穎開始了他的補課初體驗。45Please respect copyright.ＰＥＮＡＮＡ5AkNSgg8CJ
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」45Please respect copyright.ＰＥＮＡＮＡmzzp1HMxlV
45Please respect copyright.ＰＥＮＡＮＡI1B1wYILSy
「嗯，妳好。」45Please respect copyright.ＰＥＮＡＮＡGGO24sft1s
45Please respect copyright.ＰＥＮＡＮＡbAPUywAafy
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。45Please respect copyright.ＰＥＮＡＮＡigO2zoupQN
45Please respect copyright.ＰＥＮＡＮＡ92TqjCIxXK
「我應該坐哪裡？」45Please respect copyright.ＰＥＮＡＮＡpPIa8m2MAV
45Please respect copyright.ＰＥＮＡＮＡotjUonOZvn
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。45Please respect copyright.ＰＥＮＡＮＡiFpW5pSyQj
45Please respect copyright.ＰＥＮＡＮＡVfTkAIlHPD
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」45Please respect copyright.ＰＥＮＡＮＡZQy8CvL9Ly
45Please respect copyright.ＰＥＮＡＮＡwZ2aKlOEUV
曹賢穎坐在她旁邊，拿出自己的筆電。45Please respect copyright.ＰＥＮＡＮＡZCA3eF8kIJ
「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？」45Please respect copyright.ＰＥＮＡＮＡBYJQHOrOrh
「呃……我記得有聽過啦……」卞芳華一臉迷茫。45Please respect copyright.ＰＥＮＡＮＡGYBSUABhqd
45Please respect copyright.ＰＥＮＡＮＡjQmhTKVIVu
他舉起筆，寫下：45Please respect copyright.ＰＥＮＡＮＡ5pKo1FlDaV
45Please respect copyright.ＰＥＮＡＮＡz1hnoj5Rqj
x² + 5x + 6 = 045Please respect copyright.ＰＥＮＡＮＡa4ji1fiMnx
「這題怎麼解？」他問。45Please respect copyright.ＰＥＮＡＮＡz1xvVXKmj5
45Please respect copyright.ＰＥＮＡＮＡiFeQjGCxLr
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」45Please respect copyright.ＰＥＮＡＮＡ1Cozl5l8uj
45Please respect copyright.ＰＥＮＡＮＡ4UkHVqiIC8
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」45Please respect copyright.ＰＥＮＡＮＡRCUjLse3gO
45Please respect copyright.ＰＥＮＡＮＡht2a6M1mVk
曹賢穎寫下：45Please respect copyright.ＰＥＮＡＮＡyZvqBNJxJC
45Please respect copyright.ＰＥＮＡＮＡqhOoAouItp
(x + 2)(x + 3) = 045Please respect copyright.ＰＥＮＡＮＡkzfOYq397W
「所以解是？」45Please respect copyright.ＰＥＮＡＮＡtfLq9iP9Cx
45Please respect copyright.ＰＥＮＡＮＡZCzHXnH52X
「x = -2，x = -3？」45Please respect copyright.ＰＥＮＡＮＡ85cVvkEKPs
45Please respect copyright.ＰＥＮＡＮＡZUrzOpn8Av
「對，這題妳還可以。」45Please respect copyright.ＰＥＮＡＮＡS6Y99RFmin
45Please respect copyright.ＰＥＮＡＮＡhB22RjInUp
「耶～」她開心地握拳。45Please respect copyright.ＰＥＮＡＮＡerpmRazSXX
45Please respect copyright.ＰＥＮＡＮＡJv4heAjVT3
「那這題呢？」他接著寫下：45Please respect copyright.ＰＥＮＡＮＡje2BuL1Vru
45Please respect copyright.ＰＥＮＡＮＡs3LnHUMgRK
x² - 7x + 10 = 045Please respect copyright.ＰＥＮＡＮＡkJmnWkTluO
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」45Please respect copyright.ＰＥＮＡＮＡKUxWnD5PrC
45Please respect copyright.ＰＥＮＡＮＡPTv8oMTwpO
「不對，5跟2乘起來是10，但加起來是7，不是負7。」45Please respect copyright.ＰＥＮＡＮＡQF40Jjj50y
45Please respect copyright.ＰＥＮＡＮＡrD3ABbX1Nv
「哦哦對齁……」45Please respect copyright.ＰＥＮＡＮＡHYCJy5AUm8
45Please respect copyright.ＰＥＮＡＮＡawSomsawLI
「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。」45Please respect copyright.ＰＥＮＡＮＡiIWPuDz016
45Please respect copyright.ＰＥＮＡＮＡpnwNlwSTHn
「……1跟10、2跟5……喔！是-2跟-5對吧！」45Please respect copyright.ＰＥＮＡＮＡBbmncMrmFY
45Please respect copyright.ＰＥＮＡＮＡVKDos2DJAV
「嗯，不錯，那妳寫出來看看。」45Please respect copyright.ＰＥＮＡＮＡ1dpDCLopiw
45Please respect copyright.ＰＥＮＡＮＡgkJzR2qlJY
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。45Please respect copyright.ＰＥＮＡＮＡUr3BUqjKi9
45Please respect copyright.ＰＥＮＡＮＡ6QJB22IeDb
「欸不對啊……我是不是少了什麼……」45Please respect copyright.ＰＥＮＡＮＡx9etCs1FXK
45Please respect copyright.ＰＥＮＡＮＡBZwmZeHZfz
「沒有錯啊，妳做對了。」45Please respect copyright.ＰＥＮＡＮＡG82sBqy5gS
45Please respect copyright.ＰＥＮＡＮＡdrFsiGHGAX
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」45Please respect copyright.ＰＥＮＡＮＡp1xX9AlDsP
45Please respect copyright.ＰＥＮＡＮＡ26XQ0z8vB5
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。」45Please respect copyright.ＰＥＮＡＮＡMqcWklfXaq
45Please respect copyright.ＰＥＮＡＮＡo9Caa7eolK
「欸欸欸先不要我腦袋已經快燒起來了啦！」45Please respect copyright.ＰＥＮＡＮＡQuZsQZ614p
45Please respect copyright.ＰＥＮＡＮＡUGsQ1jA9uY
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……」45Please respect copyright.ＰＥＮＡＮＡ21y8gzUCMg
45Please respect copyright.ＰＥＮＡＮＡxY2NsQhjvb
「這上中學就有教了。」45Please respect copyright.ＰＥＮＡＮＡxyxxVFpMWy
45Please respect copyright.ＰＥＮＡＮＡJNb9TGGuan
「啊？」45Please respect copyright.ＰＥＮＡＮＡrRyfXzzCy0
45Please respect copyright.ＰＥＮＡＮＡ3nfSw6oid2
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。」45Please respect copyright.ＰＥＮＡＮＡH1BAETT14Z
45Please respect copyright.ＰＥＮＡＮＡ6HEsQdI40L
「配什麼……？那什麼……？」45Please respect copyright.ＰＥＮＡＮＡbjAVuitWwC
45Please respect copyright.ＰＥＮＡＮＡznadw5RKo6
他沒說話，默默地在筆記上寫下了一道更難的題目。45Please respect copyright.ＰＥＮＡＮＡ9hw6n2yz1s
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。45Please respect copyright.ＰＥＮＡＮＡgXB56AhEYM
「好了嗎？」曹賢穎耐心的看著她。45Please respect copyright.ＰＥＮＡＮＡacVzf74tg0
45Please respect copyright.ＰＥＮＡＮＡiZ9u7lK0qT
「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！」45Please respect copyright.ＰＥＮＡＮＡEne3BoehpQ
