Bona" said things started to change when he met Chinese actress/director in December (2013) and he began a campaign to be signed to her movie as he believed she could make him famous. My friend stated that Kris was absolutely sure that he would become a massive celebrity in China and was absolutely certain becoming an actor would be much better for him money and popularity wise.
"Bona" said that he began to make plans for his lawsuit and by April, he had shown her letters of support from both his mother and 2 friends who were also with his company at some point in time that he would submit to court as his proof and had prepared everything for his departure (besides telling his group and manager since he did not feel like they would support his decision to leave and he didn’t want them to stop him). I don’t know much about his case but "Bona" said she did read one of the letters and the letter claimed that Lee Soo Man was like a "father figure" in the company who had promised him he would become famous, that after he left his group back in early 2013, he had to apologize to all the members and management in order to return, member Suho was made the leader of the whole group (Kris was still leader of EXO-M publicly) and he was treated differently because of his sudden departure
