Singer and entertainer HaHa recently left a tweet congratulating and praising Yoo Jae Suk.

On August 14th, he tweeted, "I sincerely congratulate Jae Suk hyung on his birthday! The variety god, who works hard at filming even on his birthday! My... [birthday] is on August 20th."

Judging from his tweet, it looks like 'nation's MC' Yoo Jae Suk is busy filming variety programs even on his birthday, rather than taking the day off and celebrating with his friends and family.

Netizens responded, "Happy birthday, Mr. Yoo. HaHa's birthday is also coming up," "He was born in August, one of the hottest months of the year," "It's nice seeing the 'Infinity Challenge' members taking care of each other," and more.
