「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。102Please respect copyright.ＰＥＮＡＮＡ9DwaUwPDpx
「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。102Please respect copyright.ＰＥＮＡＮＡBofHROiBbI
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。102Please respect copyright.ＰＥＮＡＮＡnJtlLEWgjc
然後，她又慢慢不出現在學校了。102Please respect copyright.ＰＥＮＡＮＡdYhc5jmji9
直到，她父親回國。102Please respect copyright.ＰＥＮＡＮＡo4WUegCNUv
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。102Please respect copyright.ＰＥＮＡＮＡDOrxmzc4jW
結果下一秒她看到門口的那張臉，魂差點飛出去。102Please respect copyright.ＰＥＮＡＮＡKBP6VHzEGF
102Please respect copyright.ＰＥＮＡＮＡoFx2zMXJUC
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。102Please respect copyright.ＰＥＮＡＮＡDcBMXpX82z
102Please respect copyright.ＰＥＮＡＮＡ5M2USZyo5E
「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？」102Please respect copyright.ＰＥＮＡＮＡdCajRmNcUm
102Please respect copyright.ＰＥＮＡＮＡr6PXbTwBsb
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。102Please respect copyright.ＰＥＮＡＮＡgz3i71FD5Z
102Please respect copyright.ＰＥＮＡＮＡX9o5eNODBt
「蛤？」那一聲像審判。102Please respect copyright.ＰＥＮＡＮＡ0NPoAKfvG5
102Please respect copyright.ＰＥＮＡＮＡG1OqftuC8P
「對不起對不起對不起！」她舉雙手投降。102Please respect copyright.ＰＥＮＡＮＡIlN77mfH1O
102Please respect copyright.ＰＥＮＡＮＡFAYasjnHEX
「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。102Please respect copyright.ＰＥＮＡＮＡTVYSYWus3I
於是，卞芳華又乖乖回去上課了。102Please respect copyright.ＰＥＮＡＮＡWVZ71ABrMV
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。102Please respect copyright.ＰＥＮＡＮＡ7h97MOdVAN
「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。102Please respect copyright.ＰＥＮＡＮＡjlrZTTqu7i
102Please respect copyright.ＰＥＮＡＮＡrmrwTxO7hn
「嗯，沒問題。」曹賢穎不多話地答應了。102Please respect copyright.ＰＥＮＡＮＡoKQ2vyycTi
於是曹賢穎開始了他的補課初體驗。102Please respect copyright.ＰＥＮＡＮＡBrVTvFQVw3
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」102Please respect copyright.ＰＥＮＡＮＡn8NeaomEzo
102Please respect copyright.ＰＥＮＡＮＡLk3rRksPYR
「嗯，妳好。」102Please respect copyright.ＰＥＮＡＮＡmRxEBcixM8
102Please respect copyright.ＰＥＮＡＮＡuSeBR6VFIy
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。102Please respect copyright.ＰＥＮＡＮＡ5roS20Z7cA
102Please respect copyright.ＰＥＮＡＮＡKAXHNUq3u3
「我應該坐哪裡？」102Please respect copyright.ＰＥＮＡＮＡdyTDP5TcHZ
102Please respect copyright.ＰＥＮＡＮＡCr0b7jWNiO
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。102Please respect copyright.ＰＥＮＡＮＡrmylsqNVdm
102Please respect copyright.ＰＥＮＡＮＡlnJPhq6mQv
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」102Please respect copyright.ＰＥＮＡＮＡdFf8oQFFji
102Please respect copyright.ＰＥＮＡＮＡ1BfVQu8GQN
曹賢穎坐在她旁邊，拿出自己的筆電。102Please respect copyright.ＰＥＮＡＮＡwcbgqOVBUL
「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？」102Please respect copyright.ＰＥＮＡＮＡVb8RJfbruY
「呃……我記得有聽過啦……」卞芳華一臉迷茫。102Please respect copyright.ＰＥＮＡＮＡiz8vrk6fmX
102Please respect copyright.ＰＥＮＡＮＡ9RL9WzfztS
他舉起筆，寫下：102Please respect copyright.ＰＥＮＡＮＡ1lwwlYA1wM
102Please respect copyright.ＰＥＮＡＮＡ8MsvjIUh63
x² + 5x + 6 = 0102Please respect copyright.ＰＥＮＡＮＡztMPmqL0Xt
「這題怎麼解？」他問。102Please respect copyright.ＰＥＮＡＮＡE1UVPpfiz5
102Please respect copyright.ＰＥＮＡＮＡB8ajxxLnLB
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」102Please respect copyright.ＰＥＮＡＮＡA0TKIrRdYc
102Please respect copyright.ＰＥＮＡＮＡkjdULBMJWo
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」102Please respect copyright.ＰＥＮＡＮＡ53kOVS3TZL
102Please respect copyright.ＰＥＮＡＮＡqCssFuoKBW
曹賢穎寫下：102Please respect copyright.ＰＥＮＡＮＡuvC7lF8Rub
102Please respect copyright.ＰＥＮＡＮＡWTuO4bQGdU
(x + 2)(x + 3) = 0102Please respect copyright.ＰＥＮＡＮＡXQASWHz7lI
「所以解是？」102Please respect copyright.ＰＥＮＡＮＡdQk68Eco5n
102Please respect copyright.ＰＥＮＡＮＡuSzdm4m2pl
「x = -2，x = -3？」102Please respect copyright.ＰＥＮＡＮＡr8AZ1vvL30
102Please respect copyright.ＰＥＮＡＮＡoDywJ9uebD
「對，這題妳還可以。」102Please respect copyright.ＰＥＮＡＮＡFrVMeXJQi3
102Please respect copyright.ＰＥＮＡＮＡ5A6bmxil9x
「耶～」她開心地握拳。102Please respect copyright.ＰＥＮＡＮＡop2XM6kras
102Please respect copyright.ＰＥＮＡＮＡFTNKZbkwkx
「那這題呢？」他接著寫下：102Please respect copyright.ＰＥＮＡＮＡF1ghfQUpi6
102Please respect copyright.ＰＥＮＡＮＡOAke61Kx4H
x² - 7x + 10 = 0102Please respect copyright.ＰＥＮＡＮＡ3q7gxhf7jo
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」102Please respect copyright.ＰＥＮＡＮＡAold2eFjUz
102Please respect copyright.ＰＥＮＡＮＡwSyYKafAdU
「不對，5跟2乘起來是10，但加起來是7，不是負7。」102Please respect copyright.ＰＥＮＡＮＡ04yIKVJjHI
102Please respect copyright.ＰＥＮＡＮＡPgsWtFyySB
「哦哦對齁……」102Please respect copyright.ＰＥＮＡＮＡ9Mm1pdFmMU
102Please respect copyright.ＰＥＮＡＮＡX2alOyhjL2
「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。」102Please respect copyright.ＰＥＮＡＮＡJ17NeQkIv7
102Please respect copyright.ＰＥＮＡＮＡqHys1ysNkE
「……1跟10、2跟5……喔！是-2跟-5對吧！」102Please respect copyright.ＰＥＮＡＮＡnJCBQI5glx
102Please respect copyright.ＰＥＮＡＮＡao3ne782nM
「嗯，不錯，那妳寫出來看看。」102Please respect copyright.ＰＥＮＡＮＡGPycqVvLS4
102Please respect copyright.ＰＥＮＡＮＡFH4aIklY3R
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。102Please respect copyright.ＰＥＮＡＮＡh6cmcBu3wh
102Please respect copyright.ＰＥＮＡＮＡnhWXgpsDNl
「欸不對啊……我是不是少了什麼……」102Please respect copyright.ＰＥＮＡＮＡETANvulcfv
102Please respect copyright.ＰＥＮＡＮＡ3y3n2Y4F0D
「沒有錯啊，妳做對了。」102Please respect copyright.ＰＥＮＡＮＡe4uDllvWd4
102Please respect copyright.ＰＥＮＡＮＡnOq2zpMs4P
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」102Please respect copyright.ＰＥＮＡＮＡxYkNflV2fF
102Please respect copyright.ＰＥＮＡＮＡNvYYwbk6xA
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。」102Please respect copyright.ＰＥＮＡＮＡgnjwQKAVnR
102Please respect copyright.ＰＥＮＡＮＡdOv65BkIXP
「欸欸欸先不要我腦袋已經快燒起來了啦！」102Please respect copyright.ＰＥＮＡＮＡCrj5Raz413
102Please respect copyright.ＰＥＮＡＮＡrUU8FSSdeP
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……」102Please respect copyright.ＰＥＮＡＮＡvCaKggXswW
102Please respect copyright.ＰＥＮＡＮＡ0bxyLBVqvu
「這上中學就有教了。」102Please respect copyright.ＰＥＮＡＮＡBMQv1iz2dw
102Please respect copyright.ＰＥＮＡＮＡLFjSJoGpWG
「啊？」102Please respect copyright.ＰＥＮＡＮＡIRnxuPwMbc
102Please respect copyright.ＰＥＮＡＮＡdtvJf0WYn3
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。」102Please respect copyright.ＰＥＮＡＮＡk6HE52GYqX
102Please respect copyright.ＰＥＮＡＮＡSzHQ9H6rNX
「配什麼……？那什麼……？」102Please respect copyright.ＰＥＮＡＮＡo2iXsZSGef
102Please respect copyright.ＰＥＮＡＮＡlerzh6NYgY
他沒說話，默默地在筆記上寫下了一道更難的題目。102Please respect copyright.ＰＥＮＡＮＡaIVpfe4Y5a
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。102Please respect copyright.ＰＥＮＡＮＡJRZkkeca6I
「好了嗎？」曹賢穎耐心的看著她。102Please respect copyright.ＰＥＮＡＮＡwqg6m3lfvN
102Please respect copyright.ＰＥＮＡＮＡ9tEWSQgKh6
「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！」102Please respect copyright.ＰＥＮＡＮＡIr6gPSwwIJ
