As the younger sister of Jessica, who is currently embroiled in a conflict with SM Entertainment, Krystal is becoming the center of attention, as well.  Previously, the media was informed that Krystal was currently engaged in her drama, 'My Lovely Girl,' as normal.

In continuation, a rep was reported to have divulged on October 1 that Krystal successfully finished a day's filming for 'My Lovely Girl' on September 30 with a bright facial expression.  The rep stated, "She was not greatly agitated because she had known sufficiently beforehand about the conflict between her older sister and SM Entertainment as well asGirls' Generation."

In relation to Krystal's promotions with f(x), the rep said, "There are a lot of concerns, but we are not expecting there to be a big problem.  Especially in Krystal's case, she is a person who draws a clear line between the private and public sphere, and really desires to promote as a singer.  From the beginning, she promoted separately from her sister, so it should be okay."
