Apink CHOBOM, Apink's first sub-unit consisting of Bo Mi and Cho Rong, makes its hot debut today with "Copycat." ITZY comes back with "Sneaker" and is full of free energy. Chungha is back to help fight off the summer heat with "Sparkling," a refreshing song that sparkles and fizzes like a cold carbonated drink. SF9 returns on waves to cool you down with "Scream." This week's top two artists are WJSN with "Last Sequence" and ENHYPEN with "Future Perfect (Pass the Mic)." (Source: Viu)
