The ending of Buried Hearts episode 8 implies that Dongju is about to wreak havoc after everything he’s been through. In the previous episode, we saw the man eating cookies with cinnamon in them just to prove to Yeom that he hasn’t got his memories back. Or was it to show him that he’s willing to risk his life just to prove to Yeom that he will do whatever it takes to defeat him? I don’t know how this works, though, because he could’ve basically just died eating those cookies, but maybe he’d kept some medication ready. Or maybe Dr. Kang is in the know somehow; I did think she and Dongju might know each other from before based on the previous episode. In episode 8, Dongju is rushed to the hospital even though Ildo never called an ambulance. It’s Eunnam’s son who makes the actual call.
