On October 11 (local time), BTS successfully held its concert tour 'LOVE YOURSELF: SPEAK YOURSELF' in Riyadh, Saudi Arabia.

When V returned to the stage, he walked towards a camera, pointed at his left cheek and smiled.

In the middle of his left cheek, there was a smiley drawn on it.
Fans could not quite figure out why he drew a smiley there right then, but it was cute enough to make them smile.

It turned out V happened to have a tiny pimple next to his mole.
It seemed like he just decided that it would be fun to connect these two by making a smiley out of them.
V definitely managed to make a lot of fans smile with his cute and interesting idea.
