"Perfect Love" is MAX's 20th single on the Avex Trax label and was released on May 16, 2001. The title track was the "Kacchao" commercial song. The song debuted and peaked at #10 on the Oricon charts and is currently their last top 10 single. "Perfect Love" was to serve as the lead single from their then-upcoming fifth studio album, originally to be released on March 20, 2002. However, due to lead singer Mina's marriage and pregnancy, the album was shelved and replaced with a second greatest hits album, Precious Collection 1995–2002.
