Both movies show how traveling together affects the relationship between cold, quirky men and children in their care

ONLY IF YOU WANT TO SEE MORE OF SEO IN GUK.

This drama is completely different, and shows a really different side to Seo In Guk's acting (as well as shows you how well he fits into any role he plays).

You have to be ready for confusion, suspense and not your usual happy ending.

While it is still ongoing, I see many similarities in the characters. It's like Goblin but genders reversed, and a mix of the Grim Reaper's job.
Female lead plays a person who isn't dead and has powers. You have a male lead who is 'meant' to be with the female lead.
The effects are great, and it has to do with the dead somehow.
Definitely recommend if you enjoyed Goblin.
(Can't say much about Romantic part since I'm still watching it)

Definitely has the supernatural vibe, and beautiful cinematography.
You'll see beautiful parallels with another time period in Korean History (in this one being 1930s Korea).
The chic house, an interesting romantic story and just a lot of feels and excitement, this drama is seriously underrated, while at the same time gives you Goblin vibes.

The plot focuses on e-sports and how the main leads want to win the championship ages ago but never did since something always occurred along the way. Years later, their dream of winning the championship still exists so they continue down the road and meet the female lead along the way.

First love
Main cuple gets separated due to a family member's accident.
Third Charm have a bittersweet end.

These both have similar themes of water gods. My Poseidon reminds me a lot of The Bride of Habaek.

Both can be fun, light watches if you're not looking for something too serious.

A very strict grim reeper has to figure out something and get confronted with destinies which are entangled to his person in unexpected ways...slowly he start to struggle and to doubt some things he believed in.

A rich guy and a woman sign a relationship contract. The guy is obsessed with the girl and do everything which he thinks it is good for the FL without asking her permission. In the beginning the girl is quite unwillingly but later on...

Both are set in college and although TWM has more mature romance scenes, both dramas are similar in that one best friend is pining for the other (who is unaware and seemingly straight, as well as taken). There’s also a student-professor relationship in both dramas, though these make up smaller side stories.

Modern day fantasy stories, with ghosts hanging around. Both sets of characters deal with a muddy past. There are similarities in the cinematic directing, tone and overall feel of the two pieces.

It's not so much about reconciliation between a divorced couple, but A Beautiful Life is rather similar in their exploration of relationships. The protagonists in both films are faced with problems that require love, patience and pure tenacity to be able to endure and overcome and that's probably what draws common ground between the two. Without giving away too much however, I guess you could say that A Beautiful life is also about reconciliation between a couple as there is at some point, a bump in their relationship.

Both have rich Male lead ,poor female lead
Rich man/poor woman
Man chases woman first
Both have a childhood sweet heart whose like a family friend that admires the male lead
Both male leads are bosses to the female leads

These dramas are nothing alike but for the people who wanted to see more of The Grim Reaper and Sunny's relationship or Kwon Jung Rok and Oh Yoon Seo's relationship you should watch these two dramas. Their romance in both dramas is very different but sweet to watch. Lee Dong Wook and Yoo In Na have great chemistry :)

These two shows are not the same, but they both give me the same vibe. Both lead actors are amazing, and in both shows I was kept guessing about who the good guys were and who to trust (while knowing I was going to love the MC regardless of if they were good or not.)
