Sang-hwa

Sang-hwa is a supporting character in the 2016 apocalyptic film Train to Busan.

He is Seong-kyeon's husband and Yoon Su-yun's future father.

History
Sang-hwa is aboard the KTX for Busan with his pregnant wife, the same train in which there is Seok-woo and his daughter Su-ann. The latter wants to go to the bathroom but Sang-hwa tells her to go elsewhere because Seong-kyeong already occupies the place. It is then that the infection spreads due to a stowaway.

Panic spreads on the train and Sang-hwa, who was waiting in front of the toilet, observed people ran in all directions. His wife comes out and asks him what's going on, just to see one infected person bite another. He tries to stop the zombie and locks him in the toilet before ordering Seong-kyeong to run away before following her. Seok-woo, his daughter and all of the surviving passengers travel in a single car.

In fear, Seok-woo closes the door in the face of Sang-hwa and Seong-kyeong who are almost killed. They still manage to enter and Sang-hwa develops an aversion to the act of Seok-woo.

As the train travels to Daejeon station, Sang-hwa learns from Su-ann about her father's work and laughs at his profession. The train then stops and all the passengers exit. The military was supposed to protect them, but they didn't see anyone.

It turns out that the soldiers too were infected and started attacking the passengers. The first board the train and Yong-suk, a cowardly businessman, forces the attendant to leave. Sang-hwa (separated from Seong-kyeong), Seok-woo (separated from his daughter) and Yong-guk (separated from his friend Jin-hee) are forced to run after the train.

They manage to get in and have to save their loved ones from the zombies. They lead a fight against the Yong-guk baseball team and manage to save everyone. The group then decides to join car 15 where the other passengers are gathered. Pursued by the infected, Sang-hwa blocks access to wagon 14 while waiting for Yong-guk to open the door of wagon 15. However, Yong-suk blocked the door of this car, believing that the group was infected.

Losing time, Sang-hwa gets bitten and forces Seok-woo who was helping him to leave. He asks her to take good care of Seong-kyeong and decides to call their future daughter Yoon Su-yun.

A crying Seok-woo leaves with Seong-kyeong and the zombies finally break the door of wagon 14. Sang-hwa manages to hold them long enough for the group to get into the other wagon before completely succumbing to the infection and turn into a zombie. We don't see him as a zombie during the rest of the film, however.
