While the premises are very different, the feel of it was similar.

You have the "life back then" aspect of it; you get to experience how life was back in 1998 in Taiwan. You also have the family and friend aspect of it; you get to see the friendships developing and turning into more, as well as the relationship with the family improving. As well as the heartfelt feelings between the leads, the patience and the love.

That being said, 1988 is purely a "slice of life" drama vs. Someday also has a time travel element, as well as a murder mystery added to it.

Both of these dramas are excellent, and highly recommended.

The two male leads have the same dynamic in both dramas, where they're both fighting and the girl gets in the middle.

Their plot is very different but both the dramas have very healthy central relationships that are built out of mutual admiration, support and understanding. Main characters in both dramas are somewhat quirky and have distinct and likeable personalities. A bonus is that both do not involve love triangles.

Similar theme of girls going through ruthless preparation to avenge their closest ones. Great fighting scenes and gripping plot.

Main characters time-travelled to Joseon Dynasty from modern day. In MQ, he is a chef. In DJ, he is a doctor. They both used their own respective skills to help out people around them. They both were kinda entrepreneurs in Joseon.

I've only watched a part of First Love It's you, its giving me You Are So Sweet vibes. FLIY is VERY short though.
- both in the dubbing industry
- ML has "hidden identity"
- FL admires ML's hidden identity
- pretty light romance

I just realized these two dramas have similar vibes.
- Both are time-travel sageuk dramas
- Joseon Dynasty
- Beautiful Love Story and amazing lead couple
- Both male leads are tricked by second female leads and they thought SFLs are their childhood first loves but actually FLs are.

Both dramas are about younger woman/older man relationships,dramatic,awesome ,really well executed and beautiful .

It's set in around the same time, though in History of Crime there's no CCP and is more just crime-solving and mafia-ish vibes and in Sniper there's more elements of communist propaganda.
I find HoC and Sniper similar in that they both have this main theme of people coming together to solve crime despite having different backgrounds. There're also two main male leads (though HoC also has a FL lead who's actually quite a good character unlike the one in Sniper imo) who are friends, though in Sniper it's friends-turned-enemy and in HoC it's sortof-enemies-turned-friends. Sniper has hints of romance while HoC has none and is rather fast-paced in its development.
If you enjoy the combination of republican-era feel and crime, you'd likely enjoy both.

- jtbs drama
- older woman - young man
- problematic break up
- love in the work place ( one of the not the same office, but same building)
- hubae chase first

Circle and Awaken both similar when it comes on experimenting on human believing that it's an answer for humankind problems. Circle is about erasing PTSD completely (Post Traumatic Stress Disorder) because PTSD is a kind of mental illness that won't be cure but can be control while Awaken has making an experiment for immortality that is impossible for humankind.
It also has investigation and mystery.

Similar production team to The Eternal Love so same good story and great romantic scenes between the leads!

These are heavy hearted dramas and the similiar in ways becuz the ppl in the dramas keep lying that they dont love each other but they love each other very much

It's korean drama but It has similar story and the Go prodigy too
they are very similar in friendship relationships and Go players how their life isn't that easy and they triumph in their game that they love

The theme is almost the same. They are very similar in the plot of all, only some tiny differences.
