Why did hangeng want to leave super junior?

Answer 1

Hangeng don't want to leave suju..he just has some problems with his health and would like to take a break(holidays) but SME didn't allowed him. Then he tried to change things in his contract so that he could take a break but SME was against it...that's what i know..i don't think that he ever want to leave suju

Answer 2

He filed a lawsuit for many reasons, but the basic guidelines lie around his relationship with SM Entertainment:

• He felt he was overworked and he was tired
• He was getting sick and yet SM Entertainment did not let him attend a hospital and he was forced to perform (he attained gastritis, a stomach disease, and kidney disease, both from working too hard)
• He was not aloud to visit home to China and he became homesick
• He was forced to do things that were not on his contract
• He was treated badly by SMEnt including unfair overworking in comparison to other SM artists (there's speculation the company was being racist, but there's no way to prove something of that matter)

Other small things that don't include his relations with SMEnt:

• He had Korean "antifans" (people who didn't like him)
• He wanted to compose his own music in China
• It was still hard for him to speak in Korean

Answer 3

He was very tired and stressed, he even had a disease at that time, he wanted to rest even for just a bit but SM wouldn't let him. That's why he left. Hangeng even said, "While with SM [Entertainment], I was building so much stress that at one point, I just wanted to commit suicide."
