Gwaenchanha ~Daijoubu~ (ケンチャナ〜大丈夫〜; It's Alright ~It's Alright~) is Maeda Yuki's ninth single, and her last as a member of Hello! Project. It was released on February 25, 2009. "Gwaenchanha" (괜찮아) is a Korean word that has the same meaning as "Daijoubu."
This single is Maeda's first Korean themed single in a series of three. She collaborated with Korean song/music writer Yoo Hae-Joon and lyricist Mori Chiyoko. The duo would go on to produce all of her Korean themed singles, with the help of different composers.
The "Seoul" (ソウル) portion of track 2's title is read as "souru," and can either mean "Seoul" (a city in South Korea) or "Soul."
When the release of this single was first announced, the original track list had an additional song titled "Gwaenchanha ~Daijoubu~ Japanese +Korean mix version" (ケンチャナ〜大丈夫~(日本語+韓国語ミックスバージョン)) listed, but it was removed shortly before the release of the single.
Part of the lyrics reference the Korean winter drama Winter Sonata, which Yoo Hae-Joon was involved with.
