「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。86Please respect copyright.ＰＥＮＡＮＡgr8RY1Sdoe
「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。86Please respect copyright.ＰＥＮＡＮＡWPA7RIKlVS
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。86Please respect copyright.ＰＥＮＡＮＡca7ftKOB1a
然後，她又慢慢不出現在學校了。86Please respect copyright.ＰＥＮＡＮＡVrKJv1DhIn
直到，她父親回國。86Please respect copyright.ＰＥＮＡＮＡcjgTygaE1U
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。86Please respect copyright.ＰＥＮＡＮＡBpNHpbTFuD
結果下一秒她看到門口的那張臉，魂差點飛出去。86Please respect copyright.ＰＥＮＡＮＡEDGeHSi83k
86Please respect copyright.ＰＥＮＡＮＡ8LwUsFIuHO
「慘慘慘……爸……」她一見那熟悉的西裝身影立刻調頭飛奔上樓。86Please respect copyright.ＰＥＮＡＮＡ7v5cqoJyrB
86Please respect copyright.ＰＥＮＡＮＡmWddoWy51E
「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？」86Please respect copyright.ＰＥＮＡＮＡlW4A90itJE
86Please respect copyright.ＰＥＮＡＮＡct026zY6xZ
「我我我我……我請假……」她語無倫次地答，還在想有沒有機會逃跑。86Please respect copyright.ＰＥＮＡＮＡ3KsxTfXrRH
86Please respect copyright.ＰＥＮＡＮＡtWhD1PKLil
「蛤？」那一聲像審判。86Please respect copyright.ＰＥＮＡＮＡTxDYEDU8hZ
86Please respect copyright.ＰＥＮＡＮＡs73yYdvOtL
「對不起對不起對不起！」她舉雙手投降。86Please respect copyright.ＰＥＮＡＮＡBFD1f66Yip
86Please respect copyright.ＰＥＮＡＮＡqwgCz7P82h
「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。86Please respect copyright.ＰＥＮＡＮＡbPqPo2WKaA
於是，卞芳華又乖乖回去上課了。86Please respect copyright.ＰＥＮＡＮＡq52vsnjsJX
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。86Please respect copyright.ＰＥＮＡＮＡXoT9rLS7Cc
「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。86Please respect copyright.ＰＥＮＡＮＡIzPRztkju5
86Please respect copyright.ＰＥＮＡＮＡR8BNSgIzL5
「嗯，沒問題。」曹賢穎不多話地答應了。86Please respect copyright.ＰＥＮＡＮＡMkbquKxuuu
於是曹賢穎開始了他的補課初體驗。86Please respect copyright.ＰＥＮＡＮＡ7l2mrIRjTw
曹賢穎第一天來卞家，卞芳華開門，「呃嗨嗨～又見面啦～」86Please respect copyright.ＰＥＮＡＮＡdAeQycW87t
86Please respect copyright.ＰＥＮＡＮＡ9eKukDzggc
「嗯，妳好。」86Please respect copyright.ＰＥＮＡＮＡG1ufDHuIQv
86Please respect copyright.ＰＥＮＡＮＡ8mHPZgCd31
「嗯，妳好。」她故意學他那個簡短又冷靜的語氣。86Please respect copyright.ＰＥＮＡＮＡcNExyIlX9A
86Please respect copyright.ＰＥＮＡＮＡM0PRAqbaqr
「我應該坐哪裡？」86Please respect copyright.ＰＥＮＡＮＡfa8rGrvSca
86Please respect copyright.ＰＥＮＡＮＡc3ecudV8ZN
「隨便啦～Relax～」她擺擺手，整個人攤在沙發上像是不當回事。86Please respect copyright.ＰＥＮＡＮＡRQUgxdiiaw
86Please respect copyright.ＰＥＮＡＮＡWNsPWyRYV9
「那我坐這裡吧。聽妳爸說，妳數理程度比較差，語文還不錯。」86Please respect copyright.ＰＥＮＡＮＡh6m1rc2FfL
86Please respect copyright.ＰＥＮＡＮＡ2ANf6V2vW6
曹賢穎坐在她旁邊，拿出自己的筆電。86Please respect copyright.ＰＥＮＡＮＡxVGWRrNdV7
「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？」86Please respect copyright.ＰＥＮＡＮＡHaQ85sYfXS
「呃……我記得有聽過啦……」卞芳華一臉迷茫。86Please respect copyright.ＰＥＮＡＮＡBiLA04aTaN
86Please respect copyright.ＰＥＮＡＮＡrjZDY22UtQ
他舉起筆，寫下：86Please respect copyright.ＰＥＮＡＮＡW91eBxFZ9a
86Please respect copyright.ＰＥＮＡＮＡ1LRSgAiuJu
x² + 5x + 6 = 086Please respect copyright.ＰＥＮＡＮＡYY9glL3rfm
「這題怎麼解？」他問。86Please respect copyright.ＰＥＮＡＮＡ0Q4WQp1u2o
86Please respect copyright.ＰＥＮＡＮＡP6K1CLT7D6
卞芳華眨了眨眼，毫無把握地說：「那個……先移項？」86Please respect copyright.ＰＥＮＡＮＡiBsZuTE3Uu
86Please respect copyright.ＰＥＮＡＮＡ4yaWpaK82N
「它已經等於零了，不用移了。這種可以直接因式分解，看係數。」86Please respect copyright.ＰＥＮＡＮＡMZqz5nlvIe
86Please respect copyright.ＰＥＮＡＮＡF4PPhou2Lc
曹賢穎寫下：86Please respect copyright.ＰＥＮＡＮＡos9V5ISGtm
86Please respect copyright.ＰＥＮＡＮＡSA4ul2ZCbL
(x + 2)(x + 3) = 086Please respect copyright.ＰＥＮＡＮＡ8fHqrER3do
「所以解是？」86Please respect copyright.ＰＥＮＡＮＡ5oZbYfr5Iy
86Please respect copyright.ＰＥＮＡＮＡSL4g8xX43u
「x = -2，x = -3？」86Please respect copyright.ＰＥＮＡＮＡhA5Z787jhs
86Please respect copyright.ＰＥＮＡＮＡzbdeS3wVep
「對，這題妳還可以。」86Please respect copyright.ＰＥＮＡＮＡdYmis1xJt2
86Please respect copyright.ＰＥＮＡＮＡyRgjI14LF8
「耶～」她開心地握拳。86Please respect copyright.ＰＥＮＡＮＡ8wKmmmCshE
86Please respect copyright.ＰＥＮＡＮＡ9DUNBwUHIx
「那這題呢？」他接著寫下：86Please respect copyright.ＰＥＮＡＮＡRPQ6hLgdNs
86Please respect copyright.ＰＥＮＡＮＡeg5OTqHTW9
x² - 7x + 10 = 086Please respect copyright.ＰＥＮＡＮＡLWwVOFQkSr
卞芳華盯著題目很久：「等一下……是……10可以拆成5跟2？」86Please respect copyright.ＰＥＮＡＮＡcTYtyfOhEi
86Please respect copyright.ＰＥＮＡＮＡOp1nWDk3s4
「不對，5跟2乘起來是10，但加起來是7，不是負7。」86Please respect copyright.ＰＥＮＡＮＡdxjoYn8Vij
86Please respect copyright.ＰＥＮＡＮＡEoQL4PVWGg
「哦哦對齁……」86Please respect copyright.ＰＥＮＡＮＡLn4nzRDwdG
86Please respect copyright.ＰＥＮＡＮＡdCqoU9ftxe
「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。」86Please respect copyright.ＰＥＮＡＮＡXB9wfurV2K
86Please respect copyright.ＰＥＮＡＮＡUcvEpDz7lr
「……1跟10、2跟5……喔！是-2跟-5對吧！」86Please respect copyright.ＰＥＮＡＮＡJv79cGrfyX
86Please respect copyright.ＰＥＮＡＮＡxvpTUAKNDZ
「嗯，不錯，那妳寫出來看看。」86Please respect copyright.ＰＥＮＡＮＡNB48OaEuPH
86Please respect copyright.ＰＥＮＡＮＡ3CXuO7XRC8
她很努力地在紙上寫下：(x - 2)(x - 5) = 0，但又突然停住。86Please respect copyright.ＰＥＮＡＮＡwPodWO4yzc
86Please respect copyright.ＰＥＮＡＮＡqMY4XpViSi
「欸不對啊……我是不是少了什麼……」86Please respect copyright.ＰＥＮＡＮＡf54r4r5s2G
86Please respect copyright.ＰＥＮＡＮＡM0CRng1RwP
「沒有錯啊，妳做對了。」86Please respect copyright.ＰＥＮＡＮＡGSlsZ4sYBN
86Please respect copyright.ＰＥＮＡＮＡQZPZSBwi8s
「真的假的？」她眼睛睜大，「欸欸欸～我居然會欸！」86Please respect copyright.ＰＥＮＡＮＡRTplQtpuQo
86Please respect copyright.ＰＥＮＡＮＡkPaLuNRCVO
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。」86Please respect copyright.ＰＥＮＡＮＡ7mcNifaBzN
86Please respect copyright.ＰＥＮＡＮＡVPnQBVcOHa
「欸欸欸先不要我腦袋已經快燒起來了啦！」86Please respect copyright.ＰＥＮＡＮＡtF1Fntm5yF
86Please respect copyright.ＰＥＮＡＮＡxjEBlAn6qQ
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……」86Please respect copyright.ＰＥＮＡＮＡAXhmFG2GBq
86Please respect copyright.ＰＥＮＡＮＡIZEJod1jmB
「這上中學就有教了。」86Please respect copyright.ＰＥＮＡＮＡ1UklWhQcJ7
86Please respect copyright.ＰＥＮＡＮＡRXtR3pAG3H
「啊？」86Please respect copyright.ＰＥＮＡＮＡAgFkN9BC4a
86Please respect copyright.ＰＥＮＡＮＡRyhCnIauaU
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。」86Please respect copyright.ＰＥＮＡＮＡJzK5rk7EvS
86Please respect copyright.ＰＥＮＡＮＡ7msdoxNSo4
「配什麼……？那什麼……？」86Please respect copyright.ＰＥＮＡＮＡyqC5RA8VyR
86Please respect copyright.ＰＥＮＡＮＡQMM38SrCQD
他沒說話，默默地在筆記上寫下了一道更難的題目。86Please respect copyright.ＰＥＮＡＮＡDRQ8VP4PJZ
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。86Please respect copyright.ＰＥＮＡＮＡ1V7mFURaUM
「好了嗎？」曹賢穎耐心的看著她。86Please respect copyright.ＰＥＮＡＮＡFXGOLnQEBi
86Please respect copyright.ＰＥＮＡＮＡDF1sTgWBKN
「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！」86Please respect copyright.ＰＥＮＡＮＡEAt2COOnDp
然後按「加至主畫面」
