i know what you're pointing here, but as you can see, in almost of the said chapters, Seojin/King Kallima is being selfish; present or past. he doesn't like Princess Arie before, and now that he has their second life, he is being selfish cause he didn't get what he should have before. Dokyung/Henan is avoiding Yeonwoo/Princess Arie right now because he didn't want to repeat what had happened on their past life. he didn't want Yeonwoo/Princess Arie suffer again, so he tries to avoid Yeonwoo/Princess Arie all the time. and also you can see that Duna/Cheonghu dislikes King Kallima/Seojin beacause of what happened to her life and to Princess Arie's life.
