A Garota que Vê Cheiros (2015)

The guy can hear people thoughts and on the girl who sees scent she can identify people with her eyes do to an accident both power has to do with a car accident.

Both female protagonists got into an accident... woke up years later with a special power... and then help the police solve crimes using their powers. Both female and male protagonists work together to solve difficult crimes, and in doing so, start to develop feelings for each other. There are people after the female protagonist life. Male protagonist protect the female protagonist.

Both drama's talks about how a serial killing crime connects two people. The action in both makes the story very interesting to watch. Honestly though, who wouldn't watch hot couples fighting crimes

They have a lot of similar elements :) The story lines are not very similar but I got a similar vibe from both :) The girl who sees scents was a fantasy drama and You're all surrounded was more action, but they will similar because both dramas have the main character who decided to become a police/detective because someone from their family was murdered. Both have the cutest main leads who work together to solve the murder mystery :)

They're both mysteries involving characters that have lost a couple of their core senses.

Both drama have male and female leads solving crimes and a smart, psychopath killer after one of the main leads. The female leads are both helping the male lead solve crimes. Also main leads in both dramas have special abilities (although it's on the supernatural side for The Girl Who Sees Scents).

The Girl Who Sees Scents is more focused on the female lead who I found much stronger and more interesting than in Love me if you dare, which is more centred around the male lead. The romance is much better and more consistent in The Girl Who Sees Scents.

One of the leads has some weird power that only they can see. The other lead is a police officer.
Both dramas have supernatural aspects, TGWSS has a plotline at least.

Both dramas are revolving around cops finding a serial killer. Very good selection of actors and actresses. The Girl Who Sees Scents is comparatively much less violent than Mrs. Cops 2. It is funny how both dramas start off with a scene of the female main character helping cops to catch a criminal around the mall. More description can't be given without spoiling the stories. You just have to watch to find out!

Similar vibe. Lead has special ability that helps with solving crimes. Watching While You Were Sleeping reminded me of The Girl Who Sees Scents

Male protagonist both lost someone close to them... later in the future, they meet someone who look identical to the person they lost. Both crime/detective dramas. Both female protagonists are followed by people who are after their life because of the main male protagonist

Kwak Sun Young gets into a car accident and develops this ability of detecting a man's past from his body odors. She divorces her husband when she finds out about his long history of girlfriends. Sun Young then sets up a business where she helps women and even the police track down suspicious men and husbands.

I didn't watch it yet, but the plot seems similar to The Girl Who Sees Scents. Maybe I should watch it right now

Both dramas have something supernatural
In meloholic the main guy can see the woman’s thoughts
In GWSS the main girl can see scents
In both dramas the protagonists are linked to a case

Both leading ladies have a special ability that is linked with something that allowed them to have that special ability. There is a mystery that entangles them as the pieces fall into place. Everything gets turned upside down. Also there is that dash of romance and chemistry that keeps the pace.

Both dramas are romantic comedies with a criminal aspect to it that makes them both adorable and light-hearted while being thrilling and keeping you on the edge of your seat. Both female protagonists use their unique ability to help solve crimes and all the characters are loveable and bring a twist to the shows.
