Girl group f(x)'s member Luna revealed secret habits of member Krystal.

In MBC Music "Amazing f(x)" airing today, f(x) members spending their last night in New Zealand was revealed.

On this day, the members talked about each of their own habits but with the suggestion of one of them, they decided to imitate one another.

Krystal who turned into Amber perfectly imitated Amber who looks to the wall and does waves or does funny dances by herself. She also copied Amber's protectiveness of Sulli by saying "Our Sulli, our Sulli" even with the perfect way of talking, arousing laughter.

Luna turned into Krystal, copying the cute actions she makes when she rolls her feet on the floor and also her talking quietly.

Luna also copied Krystal who always sings with one leg slightly slanted. Other members and staff also agreed that since the beginning, Krystal had always sang with one leg a little bent.
