The main posters for 'Haha Bus' have been released.

The two main posters of 'Haha Bus', which were released on March 22 KST, show Haha, Byul, and their children Dream, Soul, and Songyi along with the bus that will become their travel partner. Haha's family is seen sitting at the bus door and looking cheerful. In addition, the playfulness in the expressions of the three siblings, Dream, Soul and Songyi, makes viewers look forward to their travels.

'Haha Bus' is a travel project prepared for Songyi, who is recovering her health after fighting a rare disease. Various passengers, including celebrity guests who will act as travel mates, will visit the old town bus and travel around the country, communicating with neighbors.

The Ha family bus trip, 'Haha Bus', will premiere on April 4 KST on ENA, AXN, and K-STAR.
