“To Me, It’s Simply You” also depicts the romance between the main couple who each comes from the city and the countryside respectively.

It shows how the main character who comes from the city has to adapt with life in the countryside while falling in love with the people there.

Not only the concepts are similar, but the vibes or the tone are also similar because they’re light, feel-good and funny.

FL writes a story that comes to life, falls in love with the main male character of her story.
..........................................

Similar dark vibes, and themes of murder and a couple against the world. ML desperately needs the FL and the FL is willing to do anything to save him.

Similar themes of murder, trauma, and guilt. Both characters are damaged and find healing in each other, even though their relationship is unusual and messed up. Both are very engrossing Japanese dramas with a similar slightly unsettling tone.

Both couples are traumatized and damaged from their past experiences and find healing and comfort in each other, despite guilt and shared trauma.

Fake brother-sister relationship between the main couple (in CL both know its not true vs. LBTI where the ML knows its fake and the FL thinks he is her brother at first). Similar vibes of their relationship as well. Both are historical setting (LBTI also has fantasy elements but CL does not).

When BYH 1st goes to the voice phishing office and got his red numbered jacket it felt like a scene from Squid Game
The basic idea was the same, guy goes undercover in a place that lied to people and used their weaknesses for money and entertainment

Similar themes including death, mental health, abuse and other darker themes .
The title of the dramas have a similar touch and intention too. Definitely Not Today & Tomorrow

They both have the plot of a uncle and aunt who want to take away their nephew for themselves since the nephew's parents are not there and at the end the leads fall in love with each other.

Harmony Forest is the 'second season' of Saessak Harmony and just as much fun! In both shows you get to know the members well and have a good laugh. While in Saessak Harmony the boys are collecting stickers and write in their diary after each episode, in Harmony Forest the staff's editing skills have improved and make everything even more funny! Both a must watch for P1eces <3

Both involve ML playing the long game in revenge by calculating it over multiple years. In both, ML assembles a group of allies to help him achieve his goal. Both have great OSTs.

Both shows center around struggling youth who decide to earn money illegally. While Hope or Dope 2's main lead is a female, Extracurricular is centered around a young man.

Both shows deal with juvenile delinquents. Both shows are also short (10 episodes) compared to other dramas.
