I started watching this drama after Sotus, and to be honest, I really couldn't sense the chemistry between the two leads in that show. I don't know if it was the characters, the acting approach from the leads, or the story, but all three factors I just mentioned were spot on in this drama. Ohm, particularly, really made every scene and interaction with the other characters believable, especially the scene on the balcony where he's begging Mes to come back + the coming out scene. The chemistry was so apparent and consistent throughout - I can't help but truly crave another drama with these two as the romantic leads. I saw a vague spoiler while watching this in regards to the ending that mentioned it was going to be a happy ending(and it was), but I have to agree with some of the viewers that said the ending was too easy, yet uneasy at the same time. I feel like an alternative ending in which they both reincarnate and meet and date each other as human beings would've been a more satisfying ending, since Mes is forever going to be 22 until he reincarnates and Than will continue to age, I can't help but think what would happen as time goes by... omg did I just think of a plot for a possible season 2.... that'd be sick actually. If they continue on from the last episode, and show their relationship now as official lovers/boyfriends/whatever up until the day Mes reincarnates - then in the distant future, they meet again.
