[Machine Translation] Former Qlair Sachiko Imai's first CD in 20 years is her first solo single! The new song, "Heartfelt Thank You", has a classic melody line. The coupling song "Last Song" is a medium tempo song with a melody reminiscent of Qlair's music. Both songs have lyrics written by the singer herself, and are ambitious works that capture her thoughts and feelings from her debut to the present. Produced by Maki Miyamae, formerly of CoCo. The music is provided by Shinji Tamura, a composer who has provided songs for SMAP, Masayuki Suzuki, Hitomi Shimatani, SKE48, NMB48, and others.
