A tragic or horrific death... "...Oh..." He doesn't know what happened, but what Doyun says resonates. If it's not normal to forget everything, then there must be a reason that Duri has. Maybe it's best that he doesn't know, but then, why does he feel like he should know? Shouldn't he know? Isn't it too selfish to slip away unburdened when someone somewhere might be grieving him alone?

"Could we try?"
