Child actress OA surprised many with her remarkable growth.

Recently, OA delivered a greeting through an account run by her mother, saying, "Hello, this is OA~ It's been a while since I last said hi. How have you been?"

She continued, "I am currently in the second year of middle school and enjoying school life~~ I hope your days are filled only with good things!! Have a great day~ Thank you."

The released photos captured the remarkable growth of OA. In particular, she boasts long legs that make it hard to believe she is in the second year of middle school, and the image of the adorable child actress from the past in "The Lady in Dignity" has completely disappeared, evoking admiration.

In response, Choi Jin-hyuk also noted, "Wow, OA, you've grown up so much. You've become so pretty!!!" Netizens also responded with comments such as, "You're so pretty," "I can't believe you've grown this much," and "You're already in the second year of middle school."

Meanwhile, OA debuted in 2015 through a commercial and has appeared in dramas including "Sisters Are Alive," "The Lady in Dignity," "Melting Me Softly," "River Where the Moon Rises," "The Green Spring That Can Be Seen from Afar," and "Police Class of You and Me."

In particular, in "The Lady in Dignity," she played the role of Princess Ari and worked closely with Jang Na-ra as mother and daughter.
