It feels like the 5th generation has officially begun now

ILLIT, who has been riding high with mega-hit songs.
They debuted as IVE's younger sister group and have been gaining massive popularity with legendary songs like "I do me" and "pop off pop off."
Also, SM's rookie girl group Hearts2Hearts made strides, but they don't seem to have surpassed the threshold of the 4th generation. They couldn't break through the ironclad defense of trendsetting girl groups like NewJeans, IVE, and aespa. However, it seems like A2O has now smashed all records and swung the doors wide open for the 5th generation.
