It seems as one of the lead's mentor is a part of the conspiracy in both shows

Both are Taiwanese drama/ movie with similar settings - high school, time travelling lovers. Even the female leads' hairstyles are similar lol

Friendly and sweet fun dramas
Bickering old friends that slowly realize their feelings for each other
Great chemistry
A Lovely Light watch

They are all 30 years-old people and the stories surround their work and their friends. Well done heartfelt rom-coms.

Similar Noir Crime Vibes

Male Lead that can fight

Both became who they were to bad circumstances or events in life

Revenge based drama

Beaten down Male Lead who exacts revenge in prison

Lots of Gambling Scenes with Brawling Scenes

Tragic circumstances push the Male Lead to a place of no coming back

Both shows have similar themes and revolve around a group of people who work together to solve ghost problems and fight against evil spirits.

Gameboys season 2 picks up on the story of Gameboys season 1 and you can really see the powerhouse of the production company

Color Rush: Creative plot! Plot is interesting and never done before. Personally, I find that the desperation that comes from monos after meeting a Probe is one that entices me to learn more about the dynamics of the relationship. Will definitely rewatch! (I do wish the portion on Mono/Probes and their history could be explored further.)

To My Star: I’ve rewatched this 6 times. Is there really a need to say more? (Though, I do wish the build up of the relationship was more explicit).

Both ML Profession are Surgeon/Doctor then after a tragedy they become a Lawyer
Both have twist/crime/thriller vibes

Both is good love story. But this is more emotional than mr queen. Because this is chinese they make lot of episodes so some episodes are boring unlike mr queen. But worth your watch.

Similar kind of broad comedy humour, and cartoonish characters. Both are satirical and both are really quite good.

[minor spoiler] Trio girls as bestfriends, and the 3 couples eventually hang out together till the end. They have completely different background and story but you will love to see the girls friendship and how they share each other love story. Plus both dramas have wedding scene at the ending due to the same cause hahah.

Both dramas are extremaly cliche and cute. ML is rich CEO who creates a fake relationship because of relative wish (grandmother and grandfather). Even the appearance of the actors is similar. FLs also have some shared traits as they pretand to be someone else.

Both of these dramas star a female protagonist who finds employment as a coroner, and helps to solve crimes.

Although IFFY is more of a comedy than TIC, both female protagonists have an interest in Forensic Pathology and solving crimes.
