[2] Man-sik, a local from the Haeundae District of Busan, unexpectedly loses Yeon-hee's father while based on a deep-sea fishing boat in the Indian Ocean during the 2004 tsunami, due to an error in judgement.

Eok-jo, now the head chairman of Busan, is pushing for redevelopment of Haeundae to designate it as a special tourist zone, causing backlash from the locals.

Dong-choon, who is Man-sik's half-brother, teams up with his son, Seung-hyun and get involved in illegal activity to earn money, but are caught by police.

Man-sik grows furious, thinking that what Dong-choon told Yeon-hee caused her to snub hanging the ribbon and attacks him.

Despite his warnings, the Disaster Prevention Agency assures him that South Korea is at no risk, but a large megatsunami forms because of a landslide near Japan and starts to travel towards Busan, where millions of beachgoers are vacationing.

A short earthquake (a minor aftershock) hits Busan before the sea starts receding from the shore, causing mass hysteria as people notice an upcoming tsunami.

After the tsunami, a memorial service honors the thousands who died, including Hyeong-sik, Hwi, Yoo-jin, and Eok-jo.

Man-sik, while cleaning the ruins of Yeon-hee's restaurant, finds the red ribbon, meaning she accepted his proposal.

Distribution rights for Haeundae was sold to Hong Kong, Taiwan, India, Indonesia, Japan, Malaysia, Philippines, Singapore, Thailand, Vietnam, the Czech Republic, Slovakia, Russia, Germany, Hungary, France, Quebec, Brazil, the United Kingdom, Australia and Turkey.
