Sweet Home is full of great characters that are easy to fall in love with, but one of season 2’s best new characters comes with a great reminder to watch a well-like K-drama from four years ago. The death of Yoon Ji-su (Park Gyu-young) in Sweet Home season 2 and the criminally low screen time of Song Kang’s Cha Hyun-su are major criticisms of Sweet Home‘s latest installment. However, new additions to Sweet Home‘s cast added more vibrancy and detail to the Sweet Home universe, complicating things further ahead of Sweet Home season 3.

From Yi-kyung’s unnamed daughter (Kim Si-a) to baseball player turned soldier Park Chan-young (Jinyoung), every new character has expanded the universe that felt so isolated in Sweet Home‘s first season. Yi-kyung’s daughter provides a new perspective for characters who are both monsters and humans to contrast Cha Hyun-su’s, while Chan-young acts as a humanization for military figures who are torn between morals and orders. Sweet Home season 2’s new characters have greatly added to the series, but one of season 2’s best new additions makes watching this romance K-drama from the past even better.

Dr. Lim Was Sweet Home Season 2’s Best New Character

He Added A New Dimension To Sweet Home

Though there are many great new characters in Sweet Home season 2, none made quite the same impression as Oh Jung-se’s Dr. Lim. From the first episode, Oh Jung-se’s performance as Dr Lim is unhinged and adds a whole new level of tension to Sweet Home. Dr, Lim’s only real care is for science, prioritizing understanding the monsters and neohumans like Cha Hyun-su over human life, which he does not value. His sadistic tendencies take pleasure in the tragedies that occur in his experiments and make him one of the most necessary yet most dangerous people in Sweet Home.

Dr. Lim may be a mad scientist, but Oh Jung-se’s performance ensures that his character is much more than that. He is a dynamic character who is not just eccentric for the sake of it. However, it is clear Dr. Lim’s only interest is his experiments and he will do anything to ensure their success, no matter how brutal. This makes Dr. Lim an interesting new addition to Sweet Home’s cast and one that could be vital in its upcoming final season.

Oh Jung-se Previously Starred In 2020’s It’s Okay To Not Be Okay

His Performance As Moon Sang-tae Is One Of His Best To Date

Though Oh Jung-se’s career is incredibly vast, one of his most memorable roles is that of Moon Sang-tae in It’s Okay to Not Be Okay. Moon Sang-tae’s autism and the continued effects of childhood trauma make him highly dependent on his younger brother, Gang-tae (Kim Soo-hyun). Though their relationship can be strained at times, it’s evident how much they care for each other and how much Sang-tae values Gang-tae and wants to protect him as his older brother, but often can’t due to how overwhelmed he feels.

It’s Okay to Not Be Okay‘s depiction of autism isn’t without its faults, but Oh Jung-se does a great job of portraying the complexities of his character. Sang-tae can be hard to understand at first, but the further It’s Okay to Not Be Okay delves into his story, the more Sang-tae’s patterns make sense. Plus, Sang-tae’s development from the beginning to the end of the series never loses sight of whom Sang-tae is as an autistic person, while also giving him the chance to grow and learn from each new experience.

Oh Jung-se’s It’s Okay To Not Be Okay & Sweet Home Characters Are Completely Different

They Are A Testament To Oh Jung-se’s Range

Sweet Home‘s Dr. Lim is a selfish and sadistic character who only cares about his experiments. Without his experiments, he loses interest and seems lethargic. However, his fascination with monsters and beratement towards humans makes him a very dangerous person, as he delights in the progression of his experiments and will not let anyone stand in the way of his success. Despite being only a minor character in Sweet Home season 2, he has proven to be a vital insight into the monsters and the next direction Sweet Home will take.

Moon Sang-tae is also vital to It’s Okay to Not Be Okay and its success. Sang-tae is passionate, much like Dr. Lim, yet his intentions are much less sadistic as he ultimately tries to do the best for his brother, although sometimes he physically cannot do so. He strives toward gaining his independence through the things he loves, such as drawing, and being seen as an equal by Moon-young (Seo Yea-ji) allows him to begin to flourish as his own person.

Despite their differences, Oh Jung-se’s portrayal of these characters really speaks to his talents as an actor. Both of these characters could have quite easily fallen into simple stereotypes that lack nuance, yet they both bounce off of the screen. They are easily two of the most memorable characters in Sweet Home and It’s Okay to Not Be Okay, and makes rewatching them an absolute must.
