=== 台灣版本 ===
台灣版《18...》新收錄了《Where Did You Go》的國語版本《寫不完的溫柔》，此曲同樣為鄧紫棋親自填詞。相較於前者的是初戀，國語版本的是第二段戀情，兩者分別為兩段戀情的分手歌<ref name=books>{{cite web| language =| publisher =| title =鄧紫棋 / 18 (平裝版)  (CD+DVD)| url =http://www.books.com.tw/exep/cdfile.php?item=0020140031| author =博客來數位科技股份有限公司| date =| accessdate =2010-05-19| deadurl =yes| archiveurl =https://web.archive.org/web/20160304205753/http://www.books.com.tw/exep/cdfile.php?item=0020140031| archivedate =2016-03-04}}</ref> ，但其後G.E.M.說所謂的第二次戀愛只是幻想，並非事實。<ref>{{cite web | language =  | publisher =  | title = G.E.M.自爆失戀 | url = http://the-sun.on.cc/cnt/entertainment/20100507/00470_032.html?pubdate=20100507 | author = on.cc | date =  | accessdate = 2010-05-27 | archive-date = 2016-03-05 | archive-url = https://web.archive.org/web/20160305005751/http://the-sun.on.cc/cnt/entertainment/20100507/00470_032.html?pubdate=20100507 | dead-url = no }}</ref>本專輯亦收錄了上一張EP《[[G.E.M.
