After last year's controversy, scandals continue to surround K-pop girl group f(x).

Shortly after allegations of Sulli's permanent departure from f(x) arose, it's been confirmed that member Victoria Song will not attend her record label's concerts in Tokyo this weekend. Reportedly, she will miss the July 5 and July 6 SMTOWN LIVE concerts due to her health condition.

According to Koreaboo, it is expected the f(x) will perform at the concert series only with Krystal Jung, Amber Liu and Park "Luna" SunYoung.

Last week, reports ignited alleging that Choi "Sulli" JinRi—after abstaining from promotional activities with f(x) since last August—would be leaving the group to pursue a career as an actress. According to K-Pop Herald, SM Entertainment has denied these allegations.

"Sulli's departure from f(x) has not yet been finalized," said the record label. "We will make a decision on Sulli's future group activities after careful consideration."

Reportedly, f(x) is currently preparing for their annual comeback, and it would potentially feature only four members of the group, without Sulli.

"We are also currently picturing a comeback in the latter half of the year for f(x), but no details have been decided yet on that either," said a rep according to allkpop.

And while SM Entertainment has denied these rumors, f(x) member Amber has reportedly unfollowed Sulli on Instagram along with labelmate and Super Junior member Heechul, leading some to believe in the restructuring of the group before their comeback.

Within the last year, several artists from SM Entertainment have exited their respective K-pop groups, including Krystal's sister Jessica, a former member of Girls' Generation.

Popular boy band, EXO is also currently promoting with nine of the original 12 members, with Kris Wu and Luhan still mired in a legal battle with SM Entertainment and Tao allegedly recovering from injury.
