Most of the recommendations suggest shows with almost the exact same plot, characters or ideas but i wanna recommend this drama.
Reason?? Because of the way the two main leads are drawn to each other. How they just end up clicking and everything flows so naturally for them with ups and downs.
I dont know they both have a similar vibe for me definitely recommend checking out MARS.

Ekin Cheng plays Sky, who races cars illegally on HK’s city streets. After an accident and he is framed for some crimes he goes to Thailand to search for his long lost father, also a racer.

It was with much difficulty that Ai Qing was able to save enough money and arrive in her dream place, Paris. As a result, she was extremely happy about this. At the same time, Zi Hao is also in Paris receiving an international fashion award, the grand prize. They both got into a big argument at a small artistic shop over a small wooden horse that they both fell in love with. In the end, with the owner's consent, Ai Qing is able to obtain the wooden horse. The accidental meeting at the airport and on the plane, cause the two of them to have an even more unfavorable impression of each other. Both were rejoicing at the fact that after this trip, they would never have to see each other again. However, who would have expected that these two people's destinies are forever intertwined tightly together.

"Wangan Midnight The Movie" based on hit manga written by Michiharu Kusunoki, the film stars Yuichi Nakamura of D-BOYS, Kazuki Kato, and Ryoko Kobayashi. The story centers on a young man named Akio Asakura, a 3rd-year high school student who salvages "Devil Z", a custom-tuned Datsun Fairlady S30Z car with a supposedly cursed history despite not having a driver's license and having no idea how to operate a manual transmission...

I absolutely don't know why I should recommend these... I just think that when the story moves on, the "feel" in these 2 dramas is very similar. Of course, MARS is more deeper and everything but still the feeling is similar. Find out for yourself and decide ^^

Chen Ling (??) and Chen Sheng (??) (both by Vic Chou) are twin brothers born out of wedlock, by a father who is their mother's brother-in-law, and has died in a racing incident. Their one childhood memory of their mother is that of a medicated cold bedbound woman, whose only words were that "in this world Sheng is the only one Ling can rely on and Ling is the only one Sheng can rely on".[1]

One day Ling meets Qi Luo, an introvert and a gentle girl, in a park where he asks her for directions. She draws the directions for Ling on the back of one of her stetches of a mother and child. Ling seeing her quietly drawing on a park bench reminds him of Sheng and becomes attracted to her. When Ling saves Qi Luo from being sexually harassed by their English teacher, she starts to open up to him. In exchange for the finished painting of 'Mother and Child', Ling promises to protect her.

Both cdramas have a theme of unique twisted plot based on a psychological thriller theme. Both dramas have leads that are committed to one another-each with their imperfections, their ghosts, that they have to overcome.

"Rikon Doukyo" centers around husband Konaka Masaru and wife Ichinose Naoko who seem to have a happy family life. All this comes to a seemingly abrupt end when the couple decides to divorce. Yet, the couple soon finds themselves living together again even though they are no longer married ...

Both are about a cool, very popular guy and a simple, but talented girl and how they due time get together.

Both FLs are withdrawn and both MLs are deeply troubled after causing or thinking they caused someone's death. Both FLs are able to see past the surface of the ML to the good person they are underneath. Both leads cross paths unexpectently and slowly help each other heal.

Both dramas involves school bullying with psychological issues making a tearful and gloomy atmosphere with sad events.

Both dramas are about two badly traumatized and emotionally fragile people who find healing in each other. Both MLs fear becoming evil and violent, both FLs are withdrawn.

I know! The stories in Mars and Love Shuffle doesn't have anything to do with each other but still..
Both dramas gave me the same feeling! They felt similar in some strange way!
So, if you liked the one I think you should definitely at least give a chance to the other! :)

Both FLs are somewhat isolated from the world, and the MLs are thought of as violent bad boys, but have good hearts. Both MLs feel responsible for someone's death, and unworthy of the FL. Both drama and movie have a similar feel.
