So basically, as I’m sure you all saw coming, Ajax has a heart attack, and Zhongli decides to donate his heart to Ajax and pass over to live in Celestia. And of course, Zhongli does this without telling him because Ajax would try to stop him if he knew. So for a brief time at the end of this chapter and the beginning of the next, no one is telling Ajax what happened to Zhongli and he’s upset. But he almost immediately figures out that Zhongli is still alive, and after some things are cleared up, they are both okay and still married and see each other every day.
