Red Velvet's Joy has been promoting a new type pf 'Hand heart' lately!

Heart shapes are an essential when it comes to the world of K-Pop, and various shapes and versions exist like the trendy 'Bite heart' created by LOONA's Chuu, or the ever-popular 'Finger heart' which has become a representative symbol of K-Pop itself in recent years. 

So what kind of heart does Joy want to share with fans?

Joy's heart is called the 'Pinky promise heart'! When made with the palms facing inward, you can easily tell that two pink-promise hands join together to form a heart. But it can also be done with the palms facing outward, forming a more fluid 'Pinky promise heart'!

Netizens commented, "I'm gonna do this heart from now on~", "Promise heart, how pretty!", "Oh the one with the palms facing out is pretty!", "The name of the heart is cute too TT", and more! Do you like the 'Pinky promise heart'?
