As has often been the case with Murashita's songs, "Yuko" is a beautifully woven creation but with that little kernel of pain. His biggest hit, "Hatsukoi"（初恋）, involved the angst surrounding that feeling of first love. "Yuko" was named after his wife, and Murashita sang about the title character, a former fiancee, shutting herself off from the protagonist. According to J-Wiki, the singer's divorce was finalized in 1985. The single itself peaked at No. 23 on Oricon.
The two songs also made it onto Murashita's 1982 album "Yume no Ato"（夢の跡）.
