'Someone is pulling the strings'

SM Entertainment said it was shocked, claiming that the lawsuit was filed while it was negotiating Luhan's future schedules and activities.

This comes after he expressed his wish to focus more on his individual activities in China more than group activities, and because of his health.

Comparing Luhan's lawsuit to Kris', SM Entertainment said the lawsuit was filed for no actual reason after the star got popular through activities with the group.

It said: "We see this as prioritising one's self and ignoring the understanding of the contract with the agency and everyone involved in the contracts and the activities with the group.

"We believe there is someone behind the scenes who is pulling the strings."

The agency said it plans to respond with its overseas partners, including those in China, and with legal experts.
