2PM member Nichkhun revealed a family picture.
On July 23, Nichkhun posted on his Twitter, "Happy Birthday my lovely sister~ July 22," along with a picture.
In the picture, Nichkhun is posing with his sister, mother, and older brother. They all have such superior beauty that it is hard to say who is better looking than others.
Nichkhun's older brother Nichan is currently working as a celebrity in Thailand, and his first younger sister is the super model in Thailand.
Internet users who saw this commented, "Superior genes," "This is what you call a family photo shoot," "Not a single one of them is inferior," and "Nichkhun looks happy to be with his family."
