"Spring Spring Spring" singer and "Superstar K4" winner Roy got emotional on Thursday as he accepted the Mnet 20's Choice Award for 20's Booming Star.

"Lately, I've troubled and worried many people," Roy said, presumably referring to the recent plagiarism accusations he faced this week.

"My heart is heavy, as well. I'm sorry. But I'll take this award to mean that I'll work even harder sincerely and more modestly."

Already accused in April of plagiarizing the songs "Where The Wind Blows" by Kim Kwang Suk and "Take On Me" by A-ha for his song "Spring Spring Spring" (or "Bom Bom Bom" in Korean) the singer-songwriter is now believed by some to be stealing from yet another composition.

The ukulele version of Acoustic Rain's "Love is Canon," features an undeniably stronger resemblance to "Spring Spring Spring" than either of the two previous songs Roy was accused of stealing from.

An online poll conducted this week by the website Allkpop found that 64 percent of those surveyed believe Roy Kim plagiarized Acoustic Rain's "Love is Canon," a striking change from the A-ha and Kim Kwang Suk accusations, widely dismissed by fans and many media outlets alike.

Yet a representative for Roy's record label CJ E&M Music told a reporter for the Seoul Broadcasting System that it is Roy who is the one being plagiarized.

"After officially confirming with the Korea Copyright Commission, the ukulele version of 'Love Is Canon' was revealed to have been registered on May 15, 2013, after Roy Kim's "Spring Spring Spring's" ("Bom Bom Bom") release on April 22, 2013," the record label rep said.

"Thus, Roy Kim's 'Spring Spring Spring' does not have anything to do with that version."

On Thursday, Roy announced he would be returning to college at Georgetown Univeristy's McDonough School of Business in Washington, D.C., in August, according to the website Soompi.

A representative from the star's record label CJ E&M claimed the decision had nothing to do with the recent round of plagiarism accusations.

"It is planned that [Roy Kim] will be going back to the U.S. in August, but it hasn't been firmly decided," the rep said.

"His departure from Korea is unrelated to the controversy. Even if he leaves briefly for his studies, his musical activities will continue. We're still deeply considering any new release of his songs."
