Ningning from aespa has become a hot topic online once again with the circulation of her pre-debut videos from her time as an SM Rookies trainee. These clips, displaying Ningning in her younger days before her official debut, have gained significant attention on Korean internet communities. Users have been captivated by her natural beauty that seems unchanged over time, except for the maturity that comes with age and her use of braces. Commenters have praised her innate charm, describing her as a genuine "natural beauty."

Online discussions have focused on how Ningning’s facial features have remained consistent, with some attributing this to her dieting efforts. Her pre-debut appearance has drawn admiration for her well-defined features that have stood out since her trainee days. People have pointed out that despite losing weight, Ningning's facial structure was distinct even then.

There have been comments highlighting the resemblance between young Ningning and present-day Ningning, noting that with certain makeup styles, she still looks like her debut self. Some have mentioned that she appeared on TV shows and had a level of fame even before her official debut, with SM Entertainment recognizing her talents early on.

The overall impression is that Ningning’s appearance has not drastically changed, likening the comparison to looking at a childhood graduation photo where one might appear a bit awkward and unpolished. In spite of this, many find her braces during her trainee days quite endearing. The article also mentions aespa's upcoming performance at the 'Mawazine' music festival in Africa.
