We need the world’s best and brightest working on this age-old puzzle: Why does heartbreak pair so well with the concept of a habit? In 2022, Steve Lacy gripped hearts with “Bad Habit,” the song that goes, “I bite my tongue, it’s a bad habit” (and even worse for fragile yearners, “I wish I knew you wanted me”). I heard Park’s “Habit” for the first time on Friday at Seoro Sarang Book Salon, an independent bookstore and hole-in-the-wall art exhibition site at the end of an alley in Gwangju’s Baegun-dong neighborhood, also known as “Mapgie Town.” The night at Seoro Sarang Book Salon was a chance for everyone to be in the same room again. He had gotten it in honor of Seoro Sarang Book Salon, whose name means “love one another” in Korean.
