Both have similar exciting and full of action movie . Main characters suddenly caught up in the crime. The storyline between the mother/father and the son is strong and balances the crazyness. Both were an entertaining movie to watch with family.

In a way, the protagonist from Godhand Teru is kind of similar to the protagonist from Mustssu: Mieru Me. They both can detect symptoms from the littlest signs. Godhand Teru has more to do with operations/medical and Mustsu: Mieru Me has to do with crime/detective.

Solving crime cases with the help of an extraordinary protagonist with a gifted nose.

Both main characters uses a unique way to solve crime. They get on other co-detectives' nerves but in the end they have a huge role in catching the criminal.

this is more comedy, but I would say the romance part is really worth swooning... A one sided love that starts from childhood that he chases her till adulthood... It's more of a noona romance but the Chemistry is a big surprise!.. There's also, action and mystery.. And a great OST's as well... Very fun to watch!..

Both movies involve the search by moms of their missing child. But 7 days is more chiller than Missing.

The Korean Drama is based off the Japanese drama that was released in 2013. same story. the Japanese drama was good, loved the songs. I think the Korean drama will have more twists in the plot. but so far looks great

It's about serial killer to, big chase, but this has time travel. It's a little more as signal.
