YMMV / Le Sserafim

• Fan Nickname: There are quite a few:
  • Chae-Chaez: Chaewon and Eunchae, due to having the "chae" syllable in their names.
  • Summerz: Chaewon and Kazuha. Both of their birthdays are in August.
  • Petalz: Sakura (cherry blossom) and Kazuha (10,000 leaves).
  • Dumb, Dumber & Dumbest Trio: Chaewon, Yunjin, and Eunchae. These three are known to be the silliest members of the entire group. They also share a dorm together.
    • Purinz/Hanlimz/Dumb & Dumber Duo: Just Chaewon and Yunjin. Both went to the same academy, although the difference is that one graduated (Chaewon) while the other dropped out and was about to prepare for a different life (Yunjin).
  • Foreigner Line: Sakura, Yunjin, and Kazuha. Both Sakura and Kazuha are Japanese, while Yunjin is Korean-American and was raised in New York.
  • Mad-Makz: Sakura and Eunchae, the oldest and youngest.
  • Eunchae Mothers Association: The four eldest members of the group. They're all protective of Eunchae and want to make sure she enjoys life both as an idol and as a normal teenager.
• Genius Bonus: Their first comeback Antifragile - released after the group endured an intense controversy over school bullying allegations leveled against Garam - has its roots in the concept of antifragility, conceptualized by mathematical statistician Nassim Nicholas Taleb, which describes systems that not only recover well from stresses, but actually thrive afterwards.
• Never Live It Down: Sakura's past works in AKB48 and HKT48 tend to be cutesier in contrast to her K-pop ones, and the other members like to poke fun at them, particularly her old solo song "Yume de Kiss Me" ("Kiss Me in A Dream").
