It is only natural for idols to mature much faster since they enter the adult society much earlier through the entertainment industry.

Therefore, young idols are put in a position to face real-life concerns while people of their age still attend school. Additionally, these idols get dolled up to portray a certain image as artists.

Recently, one netizen created a post in an online community explaining, "This was when Jennie was 21 (2016 Melon Music Awards). That's only a 1-year difference with me right now and I'm getting a reality check, lol." The netizen included a photo of BLACKPINK's Jennie when she was only 21 and explained that she is on another level.

Another netizen posted a photo of HyunA and wrote in the comments, "Should I tell you that will give you a more reality check? When HyunA was promoting 'Bubble Pop' and 'Trouble Maker,' she was only 20. How can a 20-year-old have that body? I'm..."

Other netizens also joined the online community to share their comparison and commented, "I'm 21, and I still look like a kid...how does Jennie look like that," "I really liked Jennie's hair and makeup during that performance," "That was Jennie at the 2016 Melon Music Awards," "She's the same age as me, is this for real," "I can't believe she's just one year younger than I am, how does she have a vibe like that," "I don't think it's worth comparing yourself to celebrities," "When I compare myself to idols, I really get a reality check. G-Dragon wrote 'Lies' when he was 19," and "She's so pretty here."
