Exactly two months after "Hakanaku Tsuyoku", Younha went back to her home country to release her first Korean Album entitled "고백하기 좋은 날" (Go Baek Ha Gi Jo Eun Nal, translated "The Perfect Day to Say I Love You" or literally translated "Good Day to Confess"). She recorded a MV for the third track "비밀번호 486" (Bi Mil Bun Ho 486, translated "Password 486") which stars fellow Stam artist Yoon Ji Hoo. The video featured many image changes for Younha which include her first ever kiss. The album also features a collaboration with Wheesung.
