Super Junior has formed a new unit, Super Junior-PalSamz (Super Junior-83z). Super Junior-PalSamz is a unit consisting of members Leeteuk and Heechul, both born in 1983, and attention is focused on the new chemistry the two will showcase.

Super Junior-PalSamz is set to officially debut this July and will hold a fan-con tour called "1983" covering nine regions in Asia. The tour will start in Seoul and continue to Tokyo, Bangkok, Hong Kong, Kuala Lumpur, Macau, Kaohsiung, Singapore, and Taipei. The Seoul concert will take place from July 25 to 26 at the Olympic Hall in Olympic Park, Bangi-dong.

Leeteuk and Heechul previously revealed their unit's new song "Onsaemiro" for the first time during the encore performance of Super Junior's 20th anniversary world tour, "Super Show 10 SJ-Core in Seoul."
