他把手機扔到床上，大字型地躺在床上面，望著天花板發呆了好幾分鐘，似乎想起什麼事，猛然坐了起來，身子挪到床邊，重新撿起手機，停留在聊天室人員名單的版面一段時間。423Please respect copyright.ＰＥＮＡＮＡvZKUeHGy26

他的目光停留在某幾位成員的介面中，來來回回地按進和退出，翻查了約十多分鐘，最終鎖定在某一位成員的介面上。那位成員的頭像是一個紮著馬尾的女生背著光的背影，背景是黃昏時分橘紅色的天空。423Please respect copyright.ＰＥＮＡＮＡpDUCHfOkxK

李悅楠迅速從沙發上滑下來，把掛在牆上的背包拿下往裏面翻找。他一揭開課本，趕緊翻到相片中顯示的那一頁，仔細地看了幾眼，然後俐落地把解題方法寫到一張紙上，並拍了一張照片發了出去。423Please respect copyright.ＰＥＮＡＮＡ8uuiPlfDiP

「等會請各位穿上實驗袍，戴上眼罩，先輪流洗手，洗完手在這邊拿手套並戴上。我們即將會分組進行實驗，還有不明白的地方就再問我。」化學老師一說完，同學們就按著老師的指引行動。423Please respect copyright.ＰＥＮＡＮＡ6ARos1uilt

「你們有多餘的實驗袍嗎？」正在提問的那位女生，皮膚白白淨淨，樣子甜美清純，不時還眨著那雙靈氣動人的杏眼。423Please respect copyright.ＰＥＮＡＮＡB7SQwR7sfx
423Please respect copyright.ＰＥＮＡＮＡ3853cpamGA

蕭湘雙手接過那件實驗袍，捧在胸口裏，笑盈盈地望著李悅楠的雙眼說：「李同學，我真的很感謝你！」語畢，那雙杏眼又向李悅楠眨了兩下。423Please respect copyright.ＰＥＮＡＮＡG4smCUlKbK

旁邊一位男同學小聲在李悅楠耳邊提醒說：「你把自己的袍借給對方，你就不能參與這次實驗！而且，難道你不知道這位化學老師很兇嗎？他最討厭學生沒把他話記心上！」423Please respect copyright.ＰＥＮＡＮＡbIIfxiByus
