“Bunny days” is a song aimed at girls in love, describing the “fluffy, fun time” just before a friend becomes a lover. The song will be used in a commercial for the cosmetics brand CandyDoll, produced by Masuwaka herself. She also appears in the commercial, which is scheduled to begin airing on June 16.
Masuwaka said that she has been dreaming of becoming a singer for a long time. She remarked, “The things that I couldn’t express as Masuwaka Tsubasa, I hope that I can convey them through my music activities as Milky Bunny. Please look forward to it.”
