The city of 760,000 still seems bewildered, unsure of whether, or how, to move on after the deaths of 250 students and 11 teachers. Individual suffering still radiates into the community, where a collective, haunting sadness has taken hold. Restaurants, once bustling, have lost about a third of their business; many people feel they should not have fun when so many of their neighbors are in mourning.

Among the parents, there is paralyzing grief, but also a rage that makes healing out of the question for now. Yearlong investigations suggest that the tragedy was avoidable, the result of corporate greed and lax government oversight. The families, and their community, live with the memory of some of the children’s last moments, recovered in shaky hand-held cellphone videos that document their panic as they realize the crew’s instructions to remain below deck might have doomed them.

Some say that a type of shared paranoia has set in. Students at the middle school next door to Danwon High School say school leaders have become so anxious about keeping them safe that they have halted all school trips, like the one that the high school students were on when the ferry Sewol sank, and have even banned children from running in the hallways.
