Both good bromance between an older and younger character. The older takes the younger home.... Mystery. Hidden secrets/dark past. The past comes into play in regards to their futures. Solving investigation(s) together. Learning to trust and that you are not alone.

What connects the romance is not just the emotions between men and women, but also the struggling. Stong written characthers.

Don't know, just felt like it would match since it's also college drama with youth and romance. And have kinda same vibe.

Young romancem, with family strugles/financial strugles.
FL and Ml heal each other and protect each other, falling into an endless, passionate love affair.

Another youth drama. Similar to this, cause here boy fell first and girl later. Girl helped the boy before and later they become close without her knowing. There were separation between them but it short out in time. They helped eachother and created a strong bond.

A group of friends getting school.
Young romance, with family strugles.
Fighting elements.
Both are based on a novel.

This drama is also comforting to watch, a school romance drama where the male lead is cold rather than being a warm person like fl. He also develops feelings for her slowly through her actions. No extra trouble or mess.

- Strong written characters with depth
- Female lead falls first
- Rough envirement
- The Female lead is a "fighter"

Youth, Romance, life. It's also given you a refreshing vibe and comfort, where the ml is cold but has a slowly developing feeling for the fl. And the fl is a rather warm and cute type of person. So it's not bad to compare and watch

While differing in tone and style they, share thematic similarities that make them appealing to fans of crime and mystery genres.
Both series centre around crime-solving narratives. Flex X Cop follows Jin I-soo, a wealthy chaebol heir who becomes a detective, teaming up with veteran officer Lee Gang-hyun to tackle various cases, including infiltrating a cult and uncovering familial secrets. Nine Puzzles features Jo I-na, a criminal profiler haunted by her uncle's unsolved murder, who delves into a series of killings linked by mysterious puzzle pieces.

* From Flex X Cop to Nine Puzzles: If you appreciated the investigative elements and character development in Flex X Cop, Nine Puzzles offers a deeper psychological exploration of similar themes, focusing on the protagonist's internal struggles and the intricacies of profiling.
* From Nine Puzzles to Flex X Cop: Conversely, if Nine Puzzles captivated you with its mystery and character dynamics, Flex X Cop provides a lighter, more comedic perspective on crime-solving, while still delivering engaging cases and evolving relationships.

Both feature on a school club (of mostly boys) earnestly doing silly missions and have a similar madcap "suck the marrow out of life" vibe. Not finished either so that's all I can say for now.

* Both are vertical-format dramas.
* Both are remakes of the same original drama.
* Both have their own flavour.
* if you love one may be you fall for other.
