Both shows have a group of people who decide to become the players of a mysterious game that has a big prize at stake. They have a similar vivid colors aesthetic. But Liar game is more psychological and has more clever games.

Both have a playboy ML who can charm any girl, the story revolves about how the toxic yet enchanting ML charms the reluctant FL.

Nevertheless initially make me think about CIIT because side character Yoon Sol from Nevertheless is very similar to main character Hong Soel in CIIT. Not only do they have the same name:
- their hair color is similar
- the actress playing them have similar facial features.
- they both have a tomboy style of dressing
- they are focused/hardworking/top of their class
- reserved about personal things, more introspective and perceptive attitudes
- loyal to friends, sincere and value proper communication with significant others

So yeah, basically the same person and both very endearing characters to me. Aside from that, other similarities in both dramas:
- College atmosphere that give attention to stressful academic life
- Lighthearted moments but overall melo/angsty vibe
- Focuses on psychologic/sociologic interactions between people/society
- Well-written support characters that have their own struggles
- Nontraditional, complicated male lead with questionable behavior and female lead that thinks a lot
- Main leads have problems beyond misunderstanding or not communicating

Time travelling Female Lead in both dramas. She's also very peculiar in both, though for different reasons, so the character is funny and kind of relatable. Same for the other main character, they are unusual and not your typical male leads in both show which makes an original storyline and weird situations.

Both shows revolve around different families and their relationships and feature multiple couples. Lots of family secrets to reveal in both dramas. They also focus on the relationship between parents and children.
