どうして君を好きになってしまったんだろう？CD cover

Dōshite Kimi o Suki ni Natte Shimattandarō? (どうして君を好きになってしまったんだろう？, lit. Why did I have to end up falling completely in love with you?^?), released on July 16, 2008, is Tōhōshinki's 23rd Japanese single. Approximately two months prior to the official release of the song, a leak of the recording grossed many hits on the internet.

On July 22, 2008, TVXQ became the first non-Japanese Asian artist to have three number one hits on the weekly Oricon singles chart, when their single "Dōshite Kimi o Suki ni Natte Shimattandarō?" attained the number one position with weekly sales of 68,417 copies.^[1] After Tohoshinki's invitation and performance in the prestigious Japanese year-end music festival, Kōhaku Uta Gassen, the group saw a surge in sales yet again in 2009 as well as interest in the music video on online streaming sites from Japanese viewers.

Music video

"Dōshite Kimi o Suki ni Natte Shimattandarō?" drama version MV

Two music videos were created, one featuring TVXQ group members while the other features a story. The drama version was released on June 24, 2008. According to management, the drama version was made especially for viewers who were not necessarily fans of the group and wanted to simply appreciate the song and its meaning.

The drama version MV features 20 year-old actress Fujii Mina and Murakami Kouki, in which Kouki falls in love with Mina, but Mina gets married before Kouki could confess his feelings.^[2]
