It is just unfair. It is not only Kallima who did wrong, the princess too. Unless you're glorifying betrayal upon marriage, I have no say.
She accept the marriage, then she wish to bring a lover?
She can make a statement to Kallima that she will never love him as her heart already belong to someone else. Now, should Kallima just accept him being a cuckold of his wife?
Kallima was wrong, so does the princess and her lover.
It's really weird how much sympathy there is for Seojin/Kallima. He was a shitty, deceitful guy that would rather live a lie and hurt people than just MOVE ON. I actually like Dokyung and Yeonwoo. Their past life counterparts, ehh, not as much.
