It is unlikely that any of the members of the group EXO, or their record label SM Entertainment, would argue that 2014 has been a tough year, so far.

With band members Luhan and Wu "Kris" Yifan both currently inactive after reportedly filing lawsuits against SM, the newest controversy involves allegations earlier this week that the father of EXO's Kim "Suho" Jun Myun was a member of anti-nationalist organizations in Korea.

Yet, through it all, EXO and their label appear determined to push on.

"EXO is preparing for a new album, but the time and details haven't been confirmed yet," read a statement from SM Entertainment to the Korean media outlet Newsen on Friday. "We're doing our best to create the best album."

Suho's father, Kim Yong Ha, is a professor at Soonchunhywang University in the city Ansan, South Korea.

He reportedly claims he will file a lawsuit in Seoul Central District Court on Monday, requesting an investigation by the cyber crimes unit into what he is calling an attempt to defame his son through him, according to the website allkpop.

The charges, allegedly unearthed by Internet users who have yet to be identified in published reports, accuse Kim of being a member of the New Right Union, a Korean anti-government group and a chinilpa, or sympathizer of Japan's colonial rule over the country between 1910 and 1945.

According to Kim, the claims are baseless.

"Even though I explained that the Citizens United for Better Society, which is a civic group that claims to advocate for moderate conservatives, is not the New Right Union, they ruled me a chinilpa, rallied up this outrageous reasoning because I participated in this civic group's activities, and [accused me of] being a chinilpa," the professor said, in a media statement issued on Wednesday. 

"I am not a chinilpa, nor did I do anything that could receive attention for being pro-Japanese.  My hometown is Munsu-myeon, Yeongju-si, Gyeongbuk. My family farmed for generations and had nothing to do with being pro-Japanese, even during Japanese imperialism."

Kim said the erroneous accusations even prompted Suho, who happened to be touring Japan with EXO this month, to call his father and ask him if he really was a Japanese imperialist sympathizer.

According to the Chinese news website Chinatopix, the tidal waves of accusations over Kim's associations started when a photo of the professor, known to be a vocal critic of the way the South Korean pension system reform for public workers, at a gathering of the New Right Union began circulating earlier this month.

Kim claims it was the government who originally created many of this alleged damning information about him, to silence his voice in the ongoing pension debate, but it is now resurfacing to damage his son's career.

"The portion of the forces that resisted the public officials' pension reform had systematically malicious and false content [circulated about them] on the Internet, which is not only defaming my character but also causing great pain to my son," he said. 

"No matter what, I will make them take legal responsibility."

Back in April, Kim also reportedly wrote a scathing critique of the public outcry to the Sewol ferry crash that killed over 300 people, many of them high school students on a class trip, telling the citizenry that if they wanted better oversight, they needed to pay higher taxes.

"The country and the president are not gods," the article read.
