I honestly had very little expectations for this, but it's surprisingly kept me interested so far. It's got comfortable pacing, nothing moves too fast or too slow. There is no dragging or overextending of emotional moments, it feels like everything is moving just right.
At the same time, I have to say I really dislike the tendency of kdramas to "justify" the main couple by throwing in flashbacks of how they've actually met before. Marry my husband joins other very good and prominent dramas with this cardinal cringy sin, which I completely dislike. I think it even takes away from the plot.
Otherwise, I really like and feel inspired by the storyline of having the second chance to do your life all over- and I really like that the main character does a full makeover physically and mentally. She questions her own past actions and decides she is going to fight for herself. She chooses to no longer be a pushover, and tries finding people who deserve her. I think it's really fitting to have this drama released in this day and age.
I heard it's a webtoon adaptation- I don't really know much about the webtoon so I can't comment on how well it was adapted. Regardless, the drama stands pretty well on its own, in my opinion.
