Makes the cheek heart pose, sometimes it is referred to as the Luda Cheek Heart Sign or other such names after the Kpop star that made it popular.
(Luda is a member of WJSN also known as Cosmic Girls, a South Korean girl group formed by Starship Entertainment and Yuehua Entertainment. Luda is South Korean.)

If you have access to controlnet you are better off using the controlnet I uploaded (here) with a dw_openpose and depth map. (civitai does not have either of those so I trained a LoRA for this purpose.)

Other notes about this pose:
Apparently it is the #1 pose in Japan among high-schoolers in 2022 per soranews24

Tom Cruise was seen doing this pose while promoting Top Gun Maverick in Korea

The one handed version bridges the gap between millennials and gen Z per purewow
