Ever wondered how some idols achieve their V-lines? One solution was shared by�ZE:A's Kwanghee through a photo he took with fellow member Siwan.

On February 7th, Kwanghee tweeted,�"Siwan Siwan, let's get better V-lines keke~ For the first time in a long time, we are lying together using the packs that we got as gifts. Seeing us like this makes our home seem like an aesthetician's office."

Both idols are seen wearing strange contraptions on their chins, which are apparently meant to help maintain their sharp profiles. While Kwanghee was able to deliver some aegyo for the camera, Siwan looks a little embarrassed by the exposure.

Fans commented, "So handsome!" "Please sharpen your V-lines and cut the clouds away! It's too cold!" and "Cute best friends".
