God.... I only remember 2 characters.. Like that shaman and the main lead seme... If I remember in previous story shaman and that ghost didn't end up together right??

They didn’t end up in some way (no reincarnation whatsoever) but its kinda ambiguous to say since the scene end with a possessed joohwan reaching out to the emperor.
Read here for interesting theory :

In the ending scene side stories ch.15(end) showed that joohwan performing exorcism, calling for Lee Seon the king, right? He then possessed by his previous life/spirit a.k.a Cheonseong & well…. Its all in the topic link above, this reddit user (Livinginfiction473) explained it in details(7 months ago) based on his/her/their theory/understanding but i think its accurate to say it is until(if) the author explain/clear about it later.
