On Friday, BoA uploaded a photo on her Twitter saying "My cutie younger brothers, Ddonghi BoA."

The pose was very impressive. Yesung seemed a little bit nervous, hanging his arms over BoA's shoulders. His 'manner hands' grabbed the attention. On the contrary, BoA smiled big and posed victory.

The internet users who saw the photo responded "BoA is such a cutie, " "They look good together, friendly," and "Yesung has manners."
