Super Junior leader Leeteuk shared about the troubles within its group members.

SBS 'Strong Heart' aired on June 5, featured Leeteuk who shared, “When members are within a group and start to have different schedules it’s easy to create misunderstandings,” after hearing about Sunhwa’s story of feeling neglected by SECRET members.

He continued, "Even within Super Junior members, we've had fist fights and even flipped our dinner table once while eating."

Leeteuk and Eunhyuk revealed that they've fought after getting 1st place in 'Inkigayo', said "You can't pile things up inside. Either you have to exercise together to talk things out, or get into a big fight and recover after."
