Which of Le Sserafim's newest bsides that people will like the most?

Somehow, Le Sserafim had this one "tradition" that one of their bside will stand out the most (even more than the title track itself)

- Blue Flame on fearless era

- Impurities on anti fragile era

- EPtBW on unforgiven era

So, for this 'easy' era, which bsides that you think will stands out?

seems like many are saying that 'smart' will be the one.
