King & Prince's first EP to be released on CD. This ambitious work is based on the concept of "BITTER or SWEET," inspired by the memorable phrases "Do you like me? Do you hate me?" and "Is it bitter? Is it sweet?" from the title track "So Honey." Interweaving BITTER songs and SWEET songs, this work features various forms of love songs that only the current King & Prince can sing. The title track "So Honey" is a love song into which King & Prince has poured all its heart, depicting pure romantic feelings, romantic tactics, and the hope for a happy ending. While it is an uptempo, light pop song with a summery feel, its dramatically unfolding sound and dramatic melody line strike the heart, making it a track that is set to become a new signature song for King & Prince. Limited Edition A comes with a Blu-ray. Includes one Type A trading card.
