Girl group 4minute is catching a lot of attention.

On May 12, Nam Jihyun posted on her Twitter, "Merong(meaning sticking out tongue to tease someone)," along with a photo.

In the revealed photo, 4minute members HyunA, Jiyoon, Jihyun, and Gayoon are sitting closely together while making a silly face together. Each member is sticking out her tongue with a finger under one eye, adding humor to the photo.

Internet users who saw the photo commented, "4minute posts so many odd photos," "They are so lovable," and "They feel so familiar these days.”
