Oversexualising idols regardless of their age is bad….

Oversexualising idols regardless of their age is bad. However, I feel like some people make it seem like no one under 18 should do sexy or stronger concepts. I understand how they could think that way but to me, as long as they’re over the age of consent (which is 13 in South Korea), it’s all right as long as it’s not too over the top. But then again where’s the line between too much and okay?
