Lum Sum Sum的歌詞如下：
Lum sum sum
Lum sum sum la la la
Lum sum sum la la la
我有空想帶你去走走
偶爾又偷懶不起床的後果
這樣就是光速碰著我們的分開了呀
只想享受兩人在一起好不消磨呀
在我忙時 想當公主甜蜜是足夠了吧
免考把我作模範今天想要小聰寵啦
出力因有事 是你要發揮寫愛戀信嗎
似放假誰人來幫我陪我這個天真是習慣
純情反應再照辦陪我可再度簡簡單單的耍玩
願能守候快樂短暫時光懶洋洋的看一看
(一起坐坐坐坐坐坐坐坐)
望向天空 (望望天空)
今天沒有心機要加班
(一起坐坐坐坐坐坐坐坐)
(一起躺躺躺躺躺躺躺躺)
陪我看書 (看看書本)
(一起看看書本)
(一起看看書本)
(一起看看書本)
(一起看看書本)
(一起看看書)
