Recommendations

Both FL are immortal living for centuries.
Didn't watch 2KGirl but plot seems similar to me and I loved LFTM

I watched many c drama and still continue to watching but I only recommend both of these series because they are outstanding /Fabulous the whole story plot including the whole casting every character make your attention each and every scene create curiosity what will next happen there is no comparison between the two of them but when I think about the outstanding series just two name come in my mind

Similarities

1)Outstanding Chemistry between the main lead including face expression its very tough to impress by face expression

2) Investigation and link between the cases

3) The two main lead not like each other but best friend in the end who sacrifice their own life for other

4)Create miss understanding between each other to protect his partner from evil

5) Royal Image many people follow him (in Untamed Lan Zhan has a personality and in under the power Lu Yi has that image)

6) Story of main lead background impact on his present life

I still finding another series like both of above
There are many but the standard are not high like The Untamed and Under The Power

- same comedic aspect,
- the male lead is an actor
- the female lead gets involved with the male lead and his life unwillingly
- forced cohabitation
- enemies to friends to lovers

both are about trying to live your best life and not giving up whilst fighting an illness. Plus, they're centred on how their illness affects their family and friends.

Professions of both the leads are same.
ML is trying to succeed as a wrestler
FL is struggling to become an anchorwoman

If you enjoyed watching "The Con-Heartist", you will definitely enjoy this movie too because it has a similar plot. This movie has a Drama (1 Season) and Special (SP) before, but if you are too lazy to watch the drama I think watching the movie directly is fine.

Both are about learning about how to fly. though The Eyas is more focused on the air Force and there isn't a lot of romance in The Eyas they focus more on the friendship they create while training.

Both main FM and M have age gap
They have children, in BS its only amnesia
Well the story also develop quick for the romance.

Both female leads are specially connected to nature.
Their work is also similar: Mio being a oceanographer who protects the ocean, and Mokomi who is a florist and became a person who works for plants and tree.
They both have strong passion for what they love, and both stories have good message for the public. What can you expect more of J-doramas? :D

If you like to see ML unconditional love for FL.

Similarities
Strong ML and FL
Borderline OP ML
ML will do just about anything for the Safety and Happiness of FL
ML is often misunderstood by FL
ML constantly sacrifice for FL
A ton of fight scene

Differences
The Wolf skew towards Palace scheming, while Love and Redemption is more of a Xianxia drama.

Both of the movies are about revenge. But obviously they are different. 'Inside Men: the Original' is about a gangster and a prosecutor joining hands to unveil a corruption including a journalist, a industrialist and a politician. Whereas 'A Violent Prosecutor', is all about how a wrongly accused Prosecutor tries defend himself legally with the hell of a thug.
If you liked watching 'Inside Men: the Original' , you will obviously like 'A Violent Prosecutor'.

Hope you enjoy!

'Inside Men: The Original' is the original version of the movie Inside Men. It includes extra scenes and of the movie. If you had enjoyed the movie Inside Men, you will obviously like to watch the extra scenes.

Both are drama and there is a teen romance. KyCine and SethDrea loveteams are the main actors/actresses in both shows.

- Both dramas are about married couples who are going through a divorce.
- Both dramas are about one lead becoming younger version. But in 18 again the ML really transformed to a younger by the fantasy element, but in 18 Vs 29 FL lost all the memories of her adulthood because of an accident and become younger in her mind.
- Both focus on finding lost love and second chance romance.
