If you like love stories between a mortal woman with a terminal illness and an immortal being, both have this trope. Doom is more slice of life though.

Both of these shows have supernatural elements and deal with topics like ghosts and death, and also immortal protagonists with a dark past. While there are both lots of staggering similarities, both are fantastic shows that stand alone and make a name for themselves.

Both are enemies to lover trope done right. It shows the scenes after they become boyfriends and honestly both the shows are cute.

Similar that the MC is conflicted about things. People don’t recognize ML (immortal souls) or FL (49 days) for various reasons. Both have sad parts and romance.

Same male lead in this two historical Korean drama
Both drama he played the role of layman, and eventually started to have feeling with the princess

Both of these dramas are about rich women who own large companies. Each of these women is very likable since they treat their friends and employees with absolute care, kindness, and openness. Besides business, there is also the romantic aspects of their lives, with both falling in love with a younger man. Overall, I highly recommend both of these series if you love a strong FL.

The eye color changed indicate some supernatural power is going to happen
