A very similar setting, period, and aesthetics. I am thinking that if you like one, you might like the other!

Similar genres! If you like one, you might like the other drama. I have equally enjoyed both and really liked the suspense in both! Wish we had more of these dramas!

Similar in genres! If you like one of these, you might like the other although I enjoyed hunting a bit more

Both involve a modern girl traveling back in time,
The male protagonist gives you similar vibes.
The balance between comedy, romance, suspense, and politics in both is similar and amazing. if you like one of them, you will definetly like the other.

They both contain beautiful love stories encompassed by a blindness theme

Although it is a bit different, I found these two very similar in the end. I felt like they shared the same theme, war, tragedies, heartbreaking romance, and family relations.
