Group 15& member Park Ji Min showed a selfie of herself sending Baek Yerin a message about her birthday.

On her Twitter, Park Ji Min posted, "Hey I'm coming by here and leaving a message. I heard today was Yerin's birthday. I'll end it short and thick: Happy Birthday."

In the picture she posted with her tweet, she opened her eyes wide and big and took it so up close that it showed her nostrils, eliciting laughter for the viewers.

In response, people said, "Park ji Min has sense," "Baek Yerin probably has never received a gift like this one," and "This is a funny selfie, but it's still cute."

15& finished their performances with their song, Sugar and will join the JYP Nation concert in Jamsil in August.
