「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。26Please respect copyright.ＰＥＮＡＮＡMRG6swmJoo
「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。26Please respect copyright.ＰＥＮＡＮＡIc8z1qmJyZ
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。26Please respect copyright.ＰＥＮＡＮＡCr8QG7oMQU
然後，她又慢慢不出現在學校了。26Please respect copyright.ＰＥＮＡＮＡyr0eMvyJ6v
直到，她父親回國。26Please respect copyright.ＰＥＮＡＮＡX533pwnbSP
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。26Please respect copyright.ＰＥＮＡＮＡtqMTdTTg73
結果下一秒她看到門口的那張臉，魂差點飛出去。26Please respect copyright.ＰＥＮＡＮＡb9OyMWAz3x
26Please respect copyright.ＰＥＮＡＮＡNosZ2oB2NH
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。26Please respect copyright.ＰＥＮＡＮＡlJFjmHRsA5
26Please respect copyright.ＰＥＮＡＮＡbv6QdW3tu3
「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？」26Please respect copyright.ＰＥＮＡＮＡnTQVAhfqJJ
26Please respect copyright.ＰＥＮＡＮＡE7Iz6Vli8V
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。26Please respect copyright.ＰＥＮＡＮＡUQC56Ut3Pa
26Please respect copyright.ＰＥＮＡＮＡqXeM0Pk4zJ
「蛤？」那一聲像審判。26Please respect copyright.ＰＥＮＡＮＡnlSqP9Wmkt
26Please respect copyright.ＰＥＮＡＮＡARbwtv0kGa
「對不起對不起對不起！」她舉雙手投降。26Please respect copyright.ＰＥＮＡＮＡZLMZUPqgzg
26Please respect copyright.ＰＥＮＡＮＡbejZrv6s9t
「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。26Please respect copyright.ＰＥＮＡＮＡ2oIohTeGY5
於是，卞芳華又乖乖回去上課了。26Please respect copyright.ＰＥＮＡＮＡjU0MGAom9N
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。26Please respect copyright.ＰＥＮＡＮＡrhDg6M0erZ
「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。26Please respect copyright.ＰＥＮＡＮＡlzNbQbJ6ee
26Please respect copyright.ＰＥＮＡＮＡIl4FhRrrNI
「嗯，沒問題。」曹賢穎不多話地答應了。26Please respect copyright.ＰＥＮＡＮＡTtL1DDtAYH
於是曹賢穎開始了他的補課初體驗。26Please respect copyright.ＰＥＮＡＮＡyIxcdId4Xj
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」26Please respect copyright.ＰＥＮＡＮＡ9m0l1niwZZ
26Please respect copyright.ＰＥＮＡＮＡBU1XxTu242
「嗯，妳好。」26Please respect copyright.ＰＥＮＡＮＡtaDJ0WEP8R
26Please respect copyright.ＰＥＮＡＮＡl87hMpF2VX
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。26Please respect copyright.ＰＥＮＡＮＡBjiCG6orhg
26Please respect copyright.ＰＥＮＡＮＡ5Qm1pJVqeX
「我應該坐哪裡？」26Please respect copyright.ＰＥＮＡＮＡvTic0cVeWC
26Please respect copyright.ＰＥＮＡＮＡ0mJFTN8u1V
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。26Please respect copyright.ＰＥＮＡＮＡCHA6swdzw0
26Please respect copyright.ＰＥＮＡＮＡjdJjxiLPcH
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」26Please respect copyright.ＰＥＮＡＮＡ75GQXckcgO
26Please respect copyright.ＰＥＮＡＮＡWGJJLvtiYg
曹賢穎坐在她旁邊，拿出自己的筆電。26Please respect copyright.ＰＥＮＡＮＡVktmXSY0UW
「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？」26Please respect copyright.ＰＥＮＡＮＡNxrONVbkHu
「呃……我記得有聽過啦……」卞芳華一臉迷茫。26Please respect copyright.ＰＥＮＡＮＡ1BYx69Y99i
26Please respect copyright.ＰＥＮＡＮＡIKUUKlwmqs
他舉起筆，寫下：26Please respect copyright.ＰＥＮＡＮＡNzW8vgonhl
26Please respect copyright.ＰＥＮＡＮＡUP0s1T8ij5
x² + 5x + 6 = 026Please respect copyright.ＰＥＮＡＮＡYur4iH5J3N
「這題怎麼解？」他問。26Please respect copyright.ＰＥＮＡＮＡ4jaCnBjKzQ
26Please respect copyright.ＰＥＮＡＮＡx4zG8igE3i
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」26Please respect copyright.ＰＥＮＡＮＡcy7yJphwJB
26Please respect copyright.ＰＥＮＡＮＡ9ho6K6liWT
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」26Please respect copyright.ＰＥＮＡＮＡ3tZswWYk7A
26Please respect copyright.ＰＥＮＡＮＡnqdxVX0xML
曹賢穎寫下：26Please respect copyright.ＰＥＮＡＮＡAckGHmRVka
26Please respect copyright.ＰＥＮＡＮＡ7ZL5cxQPpZ
(x + 2)(x + 3) = 026Please respect copyright.ＰＥＮＡＮＡCHoFoyMkyO
「所以解是？」26Please respect copyright.ＰＥＮＡＮＡ3Y2EPI4wEu
26Please respect copyright.ＰＥＮＡＮＡphFBQ8Upw1
「x = -2，x = -3？」26Please respect copyright.ＰＥＮＡＮＡkk88UUdUSd
26Please respect copyright.ＰＥＮＡＮＡeAAPO7WrQO
「對，這題妳還可以。」26Please respect copyright.ＰＥＮＡＮＡHYhhJvbetu
26Please respect copyright.ＰＥＮＡＮＡ4MMJTpjYef
「耶～」她開心地握拳。26Please respect copyright.ＰＥＮＡＮＡBiBmoBEO3f
26Please respect copyright.ＰＥＮＡＮＡ3hZuXz9mYX
「那這題呢？」他接著寫下：26Please respect copyright.ＰＥＮＡＮＡ5RyThdYIfJ
26Please respect copyright.ＰＥＮＡＮＡCosbJzOsZC
x² - 7x + 10 = 026Please respect copyright.ＰＥＮＡＮＡIp84yjlQwA
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」26Please respect copyright.ＰＥＮＡＮＡRUEXqXTfjp
26Please respect copyright.ＰＥＮＡＮＡW6x3PFoxiB
「不對，5跟2乘起來是10，但加起來是7，不是負7。」26Please respect copyright.ＰＥＮＡＮＡBoVZLyOs6O
26Please respect copyright.ＰＥＮＡＮＡqxLgp3r8oI
「哦哦對齁……」26Please respect copyright.ＰＥＮＡＮＡuFxu4wEdwe
26Please respect copyright.ＰＥＮＡＮＡE7QFOGnTl5
「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。」26Please respect copyright.ＰＥＮＡＮＡ6yHQYWGRPi
26Please respect copyright.ＰＥＮＡＮＡYCyqHhHBn9
「……1跟10、2跟5……喔！是-2跟-5對吧！」26Please respect copyright.ＰＥＮＡＮＡgieO36DFTl
26Please respect copyright.ＰＥＮＡＮＡw9y9g4smjo
「嗯，不錯，那妳寫出來看看。」26Please respect copyright.ＰＥＮＡＮＡ838k1eWI33
26Please respect copyright.ＰＥＮＡＮＡUEEuFpZCO6
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。26Please respect copyright.ＰＥＮＡＮＡs0HPH10B5R
26Please respect copyright.ＰＥＮＡＮＡii6jLFZJfH
「欸不對啊……我是不是少了什麼……」26Please respect copyright.ＰＥＮＡＮＡl6lrlSvYeq
26Please respect copyright.ＰＥＮＡＮＡdRVNst5baz
「沒有錯啊，妳做對了。」26Please respect copyright.ＰＥＮＡＮＡuR72kzSZ0F
26Please respect copyright.ＰＥＮＡＮＡ7j6uw9Dkq8
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」26Please respect copyright.ＰＥＮＡＮＡNd2Jp3ZtTH
26Please respect copyright.ＰＥＮＡＮＡ9OmaHsxQut
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。」26Please respect copyright.ＰＥＮＡＮＡIk4ztxzLlK
26Please respect copyright.ＰＥＮＡＮＡS2MuL7oENX
「欸欸欸先不要我腦袋已經快燒起來了啦！」26Please respect copyright.ＰＥＮＡＮＡs1kp3j9zL4
26Please respect copyright.ＰＥＮＡＮＡZODRxN3S7D
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……」26Please respect copyright.ＰＥＮＡＮＡN4VV6B8kje
26Please respect copyright.ＰＥＮＡＮＡpqGMbsHY4a
「這上中學就有教了。」26Please respect copyright.ＰＥＮＡＮＡnkzfKmfT8U
26Please respect copyright.ＰＥＮＡＮＡNllV0dIVrT
「啊？」26Please respect copyright.ＰＥＮＡＮＡqZZ14ZxUbP
26Please respect copyright.ＰＥＮＡＮＡJTFsodODN8
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。」26Please respect copyright.ＰＥＮＡＮＡiAWrr7Jj5f
26Please respect copyright.ＰＥＮＡＮＡ0fR8PCGe4A
「配什麼……？那什麼……？」26Please respect copyright.ＰＥＮＡＮＡ3tiGex1aST
26Please respect copyright.ＰＥＮＡＮＡm7rXgG1FGm
他沒說話，默默地在筆記上寫下了一道更難的題目。26Please respect copyright.ＰＥＮＡＮＡmONaLFSUjj
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。26Please respect copyright.ＰＥＮＡＮＡOJY1ogfZLM
「好了嗎？」曹賢穎耐心的看著她。26Please respect copyright.ＰＥＮＡＮＡfsq6azJj8Y
26Please respect copyright.ＰＥＮＡＮＡpItkb77YQ0
「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！」26Please respect copyright.ＰＥＮＡＮＡKa6DWpuwHw
