The female and male lead from Weightlifting Fairy both appear as supporting roles in Cheese in the Trap so if you love this actor and actress make sure to watch. I think that Lee Sung Kyung does a great job acting in both roles and it after having seen her in Cheese in the Trap and then seeing her in Weightlifting Fairy I think she is a top rate actress and I really loved her roles. She was over the top crazy in Cheese in the Trap as In Ha and she is a spunky strong girl as a female lead. Both have great story lines with strong female leads for some girl power and attractive hot male leads.
Both dramas psychological and deal with the deep issues of human nature. We see that both male characters are a mystery at first, and each character has their own battles they must fight. I loved Cheese in the Trap for the most part, but I found that Beautiful Mind far surpasses where CITT fell short, in character development.
The stories and themes are very different, but I like the two for the same reasons -- these dramas portray what it's like to be young in a way that feels very real (although they're 2 different age groups: R1997 is more highschool whereas CIT is college), their female leads are extremely relatable, and both are "slice of life" dramas that still manage to have heart-fluttering, yet realistic, romance. Also I love the female lead's best friend in both :^p ! The two dramas use flashbacks in a way that makes the story more intruiguing, instead of redundant. Finally, both dramas are tvn, so they have that slightly indie, less polished vibe, and target a young audience without being too fluffy or flaky.
Spring Waltz is a classic, older dramas and one of the famous Four Seasons. Although CITT is a comedy, it has some darker elements that remind me of the classic Spring Waltz. They're similar in the sense that they male lead id cruel to the female in the beginning and ignores her, making life tough. Later in the drama, they both come to realize they made a mistake and fall for the female leads. Both can be intense and misleading.
