Group 2PM member Nichkhun presented a surprise birthday party for his younger sister at 2PM's first concert, 'Don't Stop Can't Stop.'

By the end of the concert, Nichkhun stated, "A person I love is in this room. She's none other than my little sister." He began looking around the crowd for his sister.

"It was her birthday last week but I couldn't visit Thailand because I was preparing for this concert. However, she came to our performance today." He then asked his fans to sing a happy birthday song for her.

When his sister got up on stage, she attracted the attention of many with her tall height of 170 cm and beauty. Nichkhun held a cake prepared with his other members and sang the happy birthday song. He hugged her before she left the stage.
