Similar relationship between the main leads. Both are a perfect mix of light hearted investigation with a very subtle underlying darkness that never fully rears it head. TLDR'; easy investigative watch with great chemistry between the leads.
Both shows are about a brilliant mind - that isn't connected to the police - investigating crimes. However, whileas Kagi no Kakatta Heya dwells on locked room cases, Hard Nut! shows cases that were solved by the usage of mathematics. If you like the investigation genre, Kagi no Kakatta Heya is a sure pick for you anyway.
Yukimura Sota has spent 25 years in love with a single woman since childhood. Is it “pure love,” or is it madness born from obsession? Why does he continue to follow her from the shadows? Behind it all lies a brutal incident from 25 years ago and the secrets each of them carries.
The moment he finally breaks his long silence and comes into contact with her, his ordinary life begins to shift into something far more thrilling. People want to know everything about the person they love, but how far is too far? What if this love itself was all part of a plan…?
A love suspense story that is both the purest and the most dangerous begins.

First off can I say, I'm surprised no one mentioned this one. There is Galileo 2 but I never watched b/c Utsumi wasn't the lead.
This is a perfect example. Nanba (Hard Nut) is a student at Tokyo University for Mathematics. Yukawa (Galileo) is an assistant physics professor at Tokyo University. You'll notice the same campus scenes.
Tomoda (Hard Nut) is a straitlaced police detective presented with cases that need a mathematical need---leading to predictions on the killer. While, Utsumi (Galileo) is a straitlaced police detective presented with cases that need a physics understanding in order to predict the killer.
One glaring difference. Nanba is far more excited by the crimes while Fukawa is snobbish & void of any excitement. Tomoda is a bit more concerned for justice while Utsumi is highly sensitive for each crime.
Slight flirtation is found in both shows---well in Hard Nut it's one sided; in Galileo, it's clearly reciprocated.
If you liked or loved Hard Nut then you'll love Galileo and vice versa. This versio is basically, as I said before, is the same story but with a younger pair in Hard Nut with an interesting approach. You'll love it.

Both are episodic cases with one larger underlying case that's hinted throughout. Even though they are episodic, they aren't boring and don't drag. Plus, the characters' dynamics are kind of similar as well. Dele is more serious, better written, and the characters are more fleshed out but both are still extremely interesting and entertaining.
