「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。28Please respect copyright.ＰＥＮＡＮＡVNaC9Apxzx
「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。28Please respect copyright.ＰＥＮＡＮＡuJygZ0H0B2
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。28Please respect copyright.ＰＥＮＡＮＡeASlspbkMd
然後，她又慢慢不出現在學校了。28Please respect copyright.ＰＥＮＡＮＡZR9SRv7egk
直到，她父親回國。28Please respect copyright.ＰＥＮＡＮＡsVOAgTBPs4
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。28Please respect copyright.ＰＥＮＡＮＡQzhuvVV9fB
結果下一秒她看到門口的那張臉，魂差點飛出去。28Please respect copyright.ＰＥＮＡＮＡwKFmADHOKU
28Please respect copyright.ＰＥＮＡＮＡonJtZ4uk8f
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。28Please respect copyright.ＰＥＮＡＮＡ2ddwr2i7KA
28Please respect copyright.ＰＥＮＡＮＡ3LFTlITRz6
「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？」28Please respect copyright.ＰＥＮＡＮＡ0QE3C6oC0J
28Please respect copyright.ＰＥＮＡＮＡIgwsfNqD0s
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。28Please respect copyright.ＰＥＮＡＮＡvuwqu46RfF
28Please respect copyright.ＰＥＮＡＮＡ1IHXC8QStk
「蛤？」那一聲像審判。28Please respect copyright.ＰＥＮＡＮＡh4zArjYqGE
28Please respect copyright.ＰＥＮＡＮＡfkRU679hKk
「對不起對不起對不起！」她舉雙手投降。28Please respect copyright.ＰＥＮＡＮＡEHPd1gC33D
28Please respect copyright.ＰＥＮＡＮＡ32PtkwBJfu
「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。28Please respect copyright.ＰＥＮＡＮＡVJC4i0VKp0
於是，卞芳華又乖乖回去上課了。28Please respect copyright.ＰＥＮＡＮＡEYDZKxtFJh
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。28Please respect copyright.ＰＥＮＡＮＡSsBqEKVB2u
「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。28Please respect copyright.ＰＥＮＡＮＡBs9DJebeKD
28Please respect copyright.ＰＥＮＡＮＡYH6Qa64RZK
「嗯，沒問題。」曹賢穎不多話地答應了。28Please respect copyright.ＰＥＮＡＮＡw4DNlPoGgR
於是曹賢穎開始了他的補課初體驗。28Please respect copyright.ＰＥＮＡＮＡWitWTGlGXO
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」28Please respect copyright.ＰＥＮＡＮＡ2gERpcFS6M
28Please respect copyright.ＰＥＮＡＮＡhQpBrPjfp7
「嗯，妳好。」28Please respect copyright.ＰＥＮＡＮＡUMrTwEo23g
28Please respect copyright.ＰＥＮＡＮＡq7NdnD77ad
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。28Please respect copyright.ＰＥＮＡＮＡpF2zUUVb8J
28Please respect copyright.ＰＥＮＡＮＡFky2vDzhjQ
「我應該坐哪裡？」28Please respect copyright.ＰＥＮＡＮＡpw9ORYjgSY
28Please respect copyright.ＰＥＮＡＮＡJd6zdjpe5a
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。28Please respect copyright.ＰＥＮＡＮＡ12MNgTS1Dw
28Please respect copyright.ＰＥＮＡＮＡdChaLzwM4S
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」28Please respect copyright.ＰＥＮＡＮＡG0TaDLXbPy
28Please respect copyright.ＰＥＮＡＮＡPIqLx0HSoC
曹賢穎坐在她旁邊，拿出自己的筆電。28Please respect copyright.ＰＥＮＡＮＡ4i6A0Lzh7Z
「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？」28Please respect copyright.ＰＥＮＡＮＡpF6pBDIh7u
「呃……我記得有聽過啦……」卞芳華一臉迷茫。28Please respect copyright.ＰＥＮＡＮＡdKyWg6GFax
28Please respect copyright.ＰＥＮＡＮＡfEjRaBUXoi
他舉起筆，寫下：28Please respect copyright.ＰＥＮＡＮＡchRy1b1SiN
28Please respect copyright.ＰＥＮＡＮＡAtze2mxSs1
x² + 5x + 6 = 028Please respect copyright.ＰＥＮＡＮＡsumYFGNEc0
「這題怎麼解？」他問。28Please respect copyright.ＰＥＮＡＮＡjkdrOv2hlC
28Please respect copyright.ＰＥＮＡＮＡTFgAnBF63J
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」28Please respect copyright.ＰＥＮＡＮＡDNOb2pvVJV
28Please respect copyright.ＰＥＮＡＮＡuqSGWAk7iY
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」28Please respect copyright.ＰＥＮＡＮＡyVWwo57kDc
28Please respect copyright.ＰＥＮＡＮＡ0lez77KSFp
曹賢穎寫下：28Please respect copyright.ＰＥＮＡＮＡZsMKn6q0dw
28Please respect copyright.ＰＥＮＡＮＡreBEelfc9O
(x + 2)(x + 3) = 028Please respect copyright.ＰＥＮＡＮＡMc76lo7tts
「所以解是？」28Please respect copyright.ＰＥＮＡＮＡClPnJytDzf
28Please respect copyright.ＰＥＮＡＮＡXncCsU87MS
「x = -2，x = -3？」28Please respect copyright.ＰＥＮＡＮＡeIAHoWAY4F
28Please respect copyright.ＰＥＮＡＮＡh85Sr2pYZx
「對，這題妳還可以。」28Please respect copyright.ＰＥＮＡＮＡd52JCRl0m2
28Please respect copyright.ＰＥＮＡＮＡW1EiMrEYJV
「耶～」她開心地握拳。28Please respect copyright.ＰＥＮＡＮＡT8of9vprnb
28Please respect copyright.ＰＥＮＡＮＡQgFtMueBFY
「那這題呢？」他接著寫下：28Please respect copyright.ＰＥＮＡＮＡj4DRawkgKv
28Please respect copyright.ＰＥＮＡＮＡVRq34ZEnXE
x² - 7x + 10 = 028Please respect copyright.ＰＥＮＡＮＡI0YYvqwcpP
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」28Please respect copyright.ＰＥＮＡＮＡDafH7wPd8l
28Please respect copyright.ＰＥＮＡＮＡoxZkPR1SmH
「不對，5跟2乘起來是10，但加起來是7，不是負7。」28Please respect copyright.ＰＥＮＡＮＡTxcF0X4wBf
28Please respect copyright.ＰＥＮＡＮＡMvO5pwsZQs
「哦哦對齁……」28Please respect copyright.ＰＥＮＡＮＡJS8LM3tOfs
28Please respect copyright.ＰＥＮＡＮＡMNkVBP1wQZ
「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。」28Please respect copyright.ＰＥＮＡＮＡchoDjUNACp
28Please respect copyright.ＰＥＮＡＮＡnygOwARKOp
「……1跟10、2跟5……喔！是-2跟-5對吧！」28Please respect copyright.ＰＥＮＡＮＡXBYvz3S1UI
28Please respect copyright.ＰＥＮＡＮＡIgzhKGt53R
「嗯，不錯，那妳寫出來看看。」28Please respect copyright.ＰＥＮＡＮＡbBizoYUPr2
28Please respect copyright.ＰＥＮＡＮＡRqsh29dqkb
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。28Please respect copyright.ＰＥＮＡＮＡwLfdzc3TAQ
28Please respect copyright.ＰＥＮＡＮＡ8MJ1A5hT3p
「欸不對啊……我是不是少了什麼……」28Please respect copyright.ＰＥＮＡＮＡOUbqnuVZmD
28Please respect copyright.ＰＥＮＡＮＡaPofd7SzEA
「沒有錯啊，妳做對了。」28Please respect copyright.ＰＥＮＡＮＡ9Jr2o52Bbk
28Please respect copyright.ＰＥＮＡＮＡ7hUN09W0I1
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」28Please respect copyright.ＰＥＮＡＮＡZ3oZc7y1bO
28Please respect copyright.ＰＥＮＡＮＡ24sn1lJglH
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。」28Please respect copyright.ＰＥＮＡＮＡoIWr9WXUMw
28Please respect copyright.ＰＥＮＡＮＡqfZthYs9uW
「欸欸欸先不要我腦袋已經快燒起來了啦！」28Please respect copyright.ＰＥＮＡＮＡSJsShvSBXS
28Please respect copyright.ＰＥＮＡＮＡgJcjveICcY
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……」28Please respect copyright.ＰＥＮＡＮＡU8zmpxVfOP
28Please respect copyright.ＰＥＮＡＮＡH1h0vEDSbX
「這上中學就有教了。」28Please respect copyright.ＰＥＮＡＮＡE06Il1UwIy
28Please respect copyright.ＰＥＮＡＮＡpBZwIYXWyr
「啊？」28Please respect copyright.ＰＥＮＡＮＡ4QT0Ghrzw3
28Please respect copyright.ＰＥＮＡＮＡJda2vWKUz3
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。」28Please respect copyright.ＰＥＮＡＮＡWOV7DYvTWd
28Please respect copyright.ＰＥＮＡＮＡRdvj3Jic47
「配什麼……？那什麼……？」28Please respect copyright.ＰＥＮＡＮＡdcHbCngZBE
28Please respect copyright.ＰＥＮＡＮＡgnMUek0Lqy
他沒說話，默默地在筆記上寫下了一道更難的題目。28Please respect copyright.ＰＥＮＡＮＡrYuHDOztKb
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。28Please respect copyright.ＰＥＮＡＮＡ5Nf581Zxaf
「好了嗎？」曹賢穎耐心的看著她。28Please respect copyright.ＰＥＮＡＮＡXaX0VKLuR9
28Please respect copyright.ＰＥＮＡＮＡ0rXxq6xXt2
「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！」28Please respect copyright.ＰＥＮＡＮＡx0Be86ZKYA
