HaHa was added to the line up of K-pop stars.

On December 18ths broadcast of SBS 'I love Sunday-Running Man' Running Mans, unlike the first day in Hong Kong had individual races on the second day.

HaHa's mission was for a Hong Kong citizen to continue singing the KPOP HaHa sings. HaHa met few citizens and asked them if they knew SNSD, 2PM, and etc and found a person who knew Wondergirls but failed to have someone continue singing the song.

A Hong Kong woman HaHa met after a few fails knew HaHa. HaHa went out of his way to sing his own song 'Rosa'. However, the woman actually knew HaHa's song.

Thinking that she only knew the chorus, HaHa sang the verse part that goes 'I have to eat curry today'. To which the woman continued correctly 'I'm not going to put onions in', touching HaHa's heart.
