K-pop girl group TWICE's Mina revealed she has registered to become an organ donor on the 800th day since her debut. 

On December 27, Mina uploaded two pictures of her organ donor registration cards for both Korea and Japan.
With two photos uploaded, Mina also wrote, "Hey ONCE! Today is TWICE's 800th day since debut! Congrats congrats~ Thus, I registered as an organ donor." 

Mina was seen wearing a black turtleneck, holding organ donor's registration cards.
