「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。36Please respect copyright.ＰＥＮＡＮＡnDiMiuqIt8
「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。36Please respect copyright.ＰＥＮＡＮＡGKCSkIU0j4
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。36Please respect copyright.ＰＥＮＡＮＡz57r4ZibsQ
然後，她又慢慢不出現在學校了。36Please respect copyright.ＰＥＮＡＮＡqAnnV89M0m
直到，她父親回國。36Please respect copyright.ＰＥＮＡＮＡOCK9pBu0nM
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。36Please respect copyright.ＰＥＮＡＮＡayW3JtdDYl
結果下一秒她看到門口的那張臉，魂差點飛出去。36Please respect copyright.ＰＥＮＡＮＡe0BFCRKPlI
36Please respect copyright.ＰＥＮＡＮＡCIRehzoilS
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。36Please respect copyright.ＰＥＮＡＮＡY4fcHSLmvO
36Please respect copyright.ＰＥＮＡＮＡbnPrBhC0gF
「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？」36Please respect copyright.ＰＥＮＡＮＡQmAkXNkZNO
36Please respect copyright.ＰＥＮＡＮＡ9bbSZlMBxo
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。36Please respect copyright.ＰＥＮＡＮＡten2BWUaPY
36Please respect copyright.ＰＥＮＡＮＡlbXeTiMQtW
「蛤？」那一聲像審判。36Please respect copyright.ＰＥＮＡＮＡ4HJFluR4DF
36Please respect copyright.ＰＥＮＡＮＡ1mjfTK1ACl
「對不起對不起對不起！」她舉雙手投降。36Please respect copyright.ＰＥＮＡＮＡd3PWyvCIcK
36Please respect copyright.ＰＥＮＡＮＡCy0a6tywsx
「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。36Please respect copyright.ＰＥＮＡＮＡa70HabN09Y
於是，卞芳華又乖乖回去上課了。36Please respect copyright.ＰＥＮＡＮＡQ8T08BvVku
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。36Please respect copyright.ＰＥＮＡＮＡ3jq7RZwlio
「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。36Please respect copyright.ＰＥＮＡＮＡ37n4F7pDZx
36Please respect copyright.ＰＥＮＡＮＡkh8QmqjLhq
「嗯，沒問題。」曹賢穎不多話地答應了。36Please respect copyright.ＰＥＮＡＮＡWXjqrxSdSB
於是曹賢穎開始了他的補課初體驗。36Please respect copyright.ＰＥＮＡＮＡSNz203cO0i
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」36Please respect copyright.ＰＥＮＡＮＡJpRMSGb8hh
36Please respect copyright.ＰＥＮＡＮＡoEkfngeOx0
「嗯，妳好。」36Please respect copyright.ＰＥＮＡＮＡ2YfuU5hWGM
36Please respect copyright.ＰＥＮＡＮＡn1bWoF3GyH
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。36Please respect copyright.ＰＥＮＡＮＡFkMB5KlNzm
36Please respect copyright.ＰＥＮＡＮＡCNQ76OWoHJ
「我應該坐哪裡？」36Please respect copyright.ＰＥＮＡＮＡwtByNNk4iB
36Please respect copyright.ＰＥＮＡＮＡxllAuDlpPa
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。36Please respect copyright.ＰＥＮＡＮＡU7OfKzXSJD
36Please respect copyright.ＰＥＮＡＮＡbnlEcxBUia
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」36Please respect copyright.ＰＥＮＡＮＡ0PE1W5lEut
36Please respect copyright.ＰＥＮＡＮＡ3uQhEEEe3M
曹賢穎坐在她旁邊，拿出自己的筆電。36Please respect copyright.ＰＥＮＡＮＡ6V4DjBQJFo
「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？」36Please respect copyright.ＰＥＮＡＮＡFou85Fe7L4
「呃……我記得有聽過啦……」卞芳華一臉迷茫。36Please respect copyright.ＰＥＮＡＮＡ8qh7n11fV7
36Please respect copyright.ＰＥＮＡＮＡG4iR6Be154
他舉起筆，寫下：36Please respect copyright.ＰＥＮＡＮＡKiwLC7T5zg
36Please respect copyright.ＰＥＮＡＮＡsTaIOTgQwO
x² + 5x + 6 = 036Please respect copyright.ＰＥＮＡＮＡ3s6xFlYuFt
「這題怎麼解？」他問。36Please respect copyright.ＰＥＮＡＮＡvZA5pUj8mx
36Please respect copyright.ＰＥＮＡＮＡfK1aG3Vb6F
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」36Please respect copyright.ＰＥＮＡＮＡCpQQOrAgjd
36Please respect copyright.ＰＥＮＡＮＡ5pQhgDfk2k
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」36Please respect copyright.ＰＥＮＡＮＡvgL3tuTFVr
36Please respect copyright.ＰＥＮＡＮＡSjSeOuMT7a
曹賢穎寫下：36Please respect copyright.ＰＥＮＡＮＡmHi1RjCMIT
36Please respect copyright.ＰＥＮＡＮＡf8dQA0540Q
(x + 2)(x + 3) = 036Please respect copyright.ＰＥＮＡＮＡhqvz4mcl52
「所以解是？」36Please respect copyright.ＰＥＮＡＮＡGfz7V4AtbA
36Please respect copyright.ＰＥＮＡＮＡG1BCXyVgPZ
「x = -2，x = -3？」36Please respect copyright.ＰＥＮＡＮＡJXjzIa95rw
36Please respect copyright.ＰＥＮＡＮＡfdzvvsf3xh
「對，這題妳還可以。」36Please respect copyright.ＰＥＮＡＮＡ5dYk0PtfRX
36Please respect copyright.ＰＥＮＡＮＡOokpKbW7Tm
「耶～」她開心地握拳。36Please respect copyright.ＰＥＮＡＮＡJcfAJLmgou
36Please respect copyright.ＰＥＮＡＮＡ9hiRAp5HWo
「那這題呢？」他接著寫下：36Please respect copyright.ＰＥＮＡＮＡvJwjpYObzZ
36Please respect copyright.ＰＥＮＡＮＡXDtRr0o3qR
x² - 7x + 10 = 036Please respect copyright.ＰＥＮＡＮＡXuXEZ5QVAT
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」36Please respect copyright.ＰＥＮＡＮＡUMNQBdTNYI
36Please respect copyright.ＰＥＮＡＮＡiQo6iS55UL
「不對，5跟2乘起來是10，但加起來是7，不是負7。」36Please respect copyright.ＰＥＮＡＮＡHE6w0Bfcie
36Please respect copyright.ＰＥＮＡＮＡ29Awf7b5re
「哦哦對齁……」36Please respect copyright.ＰＥＮＡＮＡ69XKZtVMGi
36Please respect copyright.ＰＥＮＡＮＡMtR7lp3pRi
「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。」36Please respect copyright.ＰＥＮＡＮＡlX0HZRzYPH
36Please respect copyright.ＰＥＮＡＮＡ7NQFdDbp8B
「……1跟10、2跟5……喔！是-2跟-5對吧！」36Please respect copyright.ＰＥＮＡＮＡGgA0BDu0ml
36Please respect copyright.ＰＥＮＡＮＡkJLPpt62wF
「嗯，不錯，那妳寫出來看看。」36Please respect copyright.ＰＥＮＡＮＡHuInmNydYH
36Please respect copyright.ＰＥＮＡＮＡlPWODSqhyc
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。36Please respect copyright.ＰＥＮＡＮＡcv4Gn3mxXL
36Please respect copyright.ＰＥＮＡＮＡY4CjXpT6LW
「欸不對啊……我是不是少了什麼……」36Please respect copyright.ＰＥＮＡＮＡFItg8ZiGVW
36Please respect copyright.ＰＥＮＡＮＡBwggXXWTWI
「沒有錯啊，妳做對了。」36Please respect copyright.ＰＥＮＡＮＡug2KUCd7Mt
36Please respect copyright.ＰＥＮＡＮＡiX5dyaKtdo
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」36Please respect copyright.ＰＥＮＡＮＡD3AfJgEadW
36Please respect copyright.ＰＥＮＡＮＡ5gkmxEcK0J
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。」36Please respect copyright.ＰＥＮＡＮＡdS6mdXSe3r
36Please respect copyright.ＰＥＮＡＮＡ0OefiUX1XZ
「欸欸欸先不要我腦袋已經快燒起來了啦！」36Please respect copyright.ＰＥＮＡＮＡSCj5O4zyt4
36Please respect copyright.ＰＥＮＡＮＡCn4GyUyEW8
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……」36Please respect copyright.ＰＥＮＡＮＡNhmF2HRmvT
36Please respect copyright.ＰＥＮＡＮＡwaJEaU706f
「這上中學就有教了。」36Please respect copyright.ＰＥＮＡＮＡJw4te4CmXT
36Please respect copyright.ＰＥＮＡＮＡSNXRiz4QPp
「啊？」36Please respect copyright.ＰＥＮＡＮＡyzy095Lwi5
36Please respect copyright.ＰＥＮＡＮＡliIauAjPWH
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。」36Please respect copyright.ＰＥＮＡＮＡqK82RApZMw
36Please respect copyright.ＰＥＮＡＮＡphKtzlqr3d
「配什麼……？那什麼……？」36Please respect copyright.ＰＥＮＡＮＡ393mDJpiEt
36Please respect copyright.ＰＥＮＡＮＡ4FsTzcomMk
他沒說話，默默地在筆記上寫下了一道更難的題目。36Please respect copyright.ＰＥＮＡＮＡM2Je9ZjYb0
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。36Please respect copyright.ＰＥＮＡＮＡvniHxv7iRG
「好了嗎？」曹賢穎耐心的看著她。36Please respect copyright.ＰＥＮＡＮＡ8KtanJpfsu
36Please respect copyright.ＰＥＮＡＮＡUiDdJJYvna
「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！」36Please respect copyright.ＰＥＮＡＮＡhwTc4di7R3
