Released October 27, 2010 This duet single was realized due to a love call to Tomochika, who is known for her singing ability. "Shiawase no Motomekata" is a Showa-era kayokyoku-style song written by the lyricist and composer duo Toyohisa Araki and Takao Horiuchi, depicting the bittersweet and fleeting "shape of love" of adults. "Tokai no Tenshi-tachi" was also handled by the same lyricist and composer duo as "Shiawase no Motomekata," and is a glamorous cover of the song released in 1992 by Horiuchi and Eun-Sook Kye. 01.
