4minute's Sohyun shared a photo on Twitter that made fans wonder if she was really the group's youngest member.

Kwon Sohyun posted on the 28th KST, "Today's a good day as well! Off to my schedule." Her outfit gave her a more mature look as fans commented, "The youngest member who is both cute and mature," "I think you're becoming more womanly after your unnis," and "Grow up well please."

She's no longer that cute little maknae, how does it feel to see your idols grow up?
