'Entertainment Relay' met up with the hilarious trio on the set of their 'Coca-Cola' CF. While HaHa was being distracted by the reporter, Noh Hong Chul and Jung Jun Ha came from behind him with a birthday cake. HaHa was so touched that he gave each of them an 'American-style greeting'. 

HaHa then gave a message to the most important woman in his life Byul as he shared, "Thank you. I love you, Dream's mom. This is my first birthday as a husband and father. I am really thankful to spend it as a family."

HaHa also noticed Noh Hong Chul looking brighter and more talkative than usual which was all thanks to a hot CF model on set. The reporter tried to hook Noh Hong Chul and the model up to which Noh Hong Chul joked, "Are you Dispatch?" HaHa also shared how precious the moment of his son's birth is and how Dream farts like an adult.
