This baby-faced actress playing a primary school girl in a new web drama is actually a 20-year-old-woman.

Korean Kim Yoon Hee looks so young that she successfully plays the role of an elementary school student in the film titled “Bad Boy”.

A clip from the movie in which three boys throw stones at her before one then apologises and puts a plaster on her head was widely shared with many commenting on her realistic performance.

The story centres around the fact that the character she plays, Yoon-Hee, is teased because she is from a poor background and at some stage she meets a boy called Jae Hyeok.

He is seen being one of the boys who are impressed at the way he chases her away from the community sandpit before then going up to her when she returns and apologising for throwing a stone.

She was able to play the child 10 years younger than her because of her small face, big eyes and childish figure.

She is also active on TikTok and Instagram with followers noting that if anybody had access to the fountain of youth – it was probably her.
