This is the debut song of a brand new girl group. They are amazing. If あなた mix BLACKPINK and TWICE together, あなた have this group. Girl groups are truly dominating 2019. The タイトル means "Chocolate Candy" in French.
This is quite possibly BTS' best song ever. The only ones I can think of that could compare are Baepsae and Spine Breaker. Needless to say, this is one of my お気に入り 防弾少年団 songs.
