Singer Seo In Guk's 'frowning face' 3-set is catching much attention.

Recently, one online community forum posted caption "Seo In Guk's naive frowning face" along with pictures of Seo In Guk.

The pictures were from Seo In Guk's new song "BOMTANABA" music video and he is making a whiny, frowning face in all of them.

Seo In Guk was acting as a man who was waiting for the reply after sending a message to a girl he likes, so he was rolling around in bed or pouting his lips in his desperation.
