一個人想著一個人 (終極一班2) - 曾沛慈

曾沛慈演唱的《一個人想著一個人》是 2012 年偶像劇《終極一班 2》片尾曲，由張簡君偉詞曲創作。這首作品橫掃各大數位排行榜冠軍，並榮登第九屆 KKBOX 風雲榜華語單曲榜第三名。副歌連用七個「一」字營造煢煢孑立的孤單情緒，搭配曾沛慈情緒收放恰到好處的詮釋，成為華語抒情樂壇歷久不衰的經典代表作。這首歌不僅讓曾沛慈從戲劇成功回歸歌手身份，更成為無數人心中關於思念與孤單的時代記憶。

"Thinking of Someone Alone" (一個人想著一個人) by Pets Tseng is the iconic ending theme of the 2012 Taiwanese drama "KO One Return 2," written and composed by Alex Chang Jien. The song dominated multiple digital charts upon release and reached 3rd place on the 9th KKBOX Music Awards Top 100 Mandarin Songs chart. The chorus famously uses the word "one" (一) seven times to evoke a deep sense of loneliness and longing. Combined with Pets Tseng's emotionally restrained yet heartfelt vocal delivery, this ballad has become one of the most beloved and enduring Mandarin love songs of the past decade. The song marked a turning point in Pets Tseng's career, transitioning her from drama actress back to her roots as a singer.
