From what I read in spoilers emperor regained consciousness and he was angry at the ml for what he did to uke and how much he tortured him in prison and believed whatever that fking mistress told him like a fool when it was that mistress who poisoned the emperor. So she uke asked to get a divorce from ml to emperor, emperor couldn't refuse and agreed, after some regretting in ml side,(I personally want him to regret more like going crazy fk)anyway so they still end up together but uke never got married to ml again, even when ml proposed he never agreed so I guess that's good, so if ml ever does anything uke can just leave(>y<) coz he doesn't belong to ml legally anymore sooo
