Kim Young Kwang has opened up about his experience working with Chae Soo Bin in Netflix’s romantic comedy Take Charge of My Heart, praising her playful personality, adaptability and depth as an actress. The actor revealed that her natural charm helped him feel more comfortable performing romantic scenes, allowing their on-screen chemistry to develop as filming progressed.
Released on Netflix on October 9, 2026, the series follows an unusual romance between a man whose artificial heart is running out of power and a woman who possesses electrical abilities. The drama attracted early international attention, recording 3 million viewing hours within three days of its release and reaching No. 3 on Netflix’s Global Top 10 Non-English TV Shows list.
Kim Young Kwang Calls Chae Soo Bin Cute And Easy To Work With
During a recent interview, Kim Young Kwang spoke warmly about his first collaboration with Chae Soo Bin. He explained that she responded naturally to his jokes and playful behaviour, even when scenes changed unexpectedly between rehearsals and actual filming.
The actor admitted that he initially felt shy during certain romantic moments. However, Chae’s ability to adapt to spontaneous changes helped him relax and perform more naturally. He also credited her personality with making their romantic scenes feel more convincing.
Kim affectionately described Chae as cute and said her charm encouraged him to become more expressive around her. He also recalled that she often found somewhere to lie down or lean against while on set, comparing her relaxed habits to those of a koala.
Her hairstyle in the series also caught his attention. Kim felt that her perm suited her particularly well and complemented the character she portrayed. The actor’s comments reflect how the pair developed a comfortable working relationship, allowing their characters’ growing affection to translate into the playful energy that drives the series.
How The Co-Stars Built Their On-Screen Chemistry
According to Kim, he and Chae did not immediately joke around with each other when filming began. Their relationship gradually became more relaxed as they spent additional time together and worked through the evolving emotional stages of their characters.
As the shoot progressed, they began playing pranks on each other and responding more freely to spontaneous moments. Their playful interactions became noticeable to people around them, who compared their dynamic to characters from Zootopia or the familiar comic rivalry of Tom and Jerry.
Kim said he believed they had developed good chemistry, and he appreciated how easily Chae responded to his playful approach. Their ability to adjust to unexpected changes was especially useful in a romantic comedy, where small reactions and natural timing can make a significant difference.
He also explained that the director wanted the series to embrace familiar romantic-comedy conventions rather than avoid them. Although some scenes initially felt exaggerated or embarrassing, Kim trusted the director’s vision and committed to the style. The result was a production in which both actors could lean into the genre’s playful, heart-fluttering moments while building a believable connection between their characters.

Kim Young Kwang Praises Chae Soo Bin’s Acting Depth
Beyond her cheerful personality, Kim discovered qualities in Chae that changed his initial impression of her. He had first thought of her as petite, youthful and innocent, but working closely with her revealed how carefully she approached her performances. He praised the way she thought deeply about individual scenes and considered different possibilities for portraying her character. Rather than simply following the script, she asked questions about how particular choices might affect the emotional realism of a moment.
Kim described her as an actress with considerable depth and a strong desire to make her performances feel authentic. He also appreciated the encouragement she offered when he felt awkward or nervous during romantic scenes. Chae would reassure him that everything was fine, helping him become more comfortable in situations that required a greater degree of emotional expression. That support, combined with her flexibility on set, helped strengthen their collaboration.
For Kim, the experience demonstrated that successful screen chemistry depends on more than a convincing romantic storyline. Trust, responsiveness and a willingness to support one another can be just as important in making a fictional relationship feel genuine.

Kim also discussed why he accepted Take Charge of My Heart after spending considerable time playing darker characters and villains. He wanted to return to lighter roles that would allow him to explore a different side of his acting. He explained that playing villains often required him to focus on creating tension, leaving fewer opportunities for laughter. Working on a romantic comedy brought back a sense of excitement and made the filming experience feel refreshing.
The series combines romance with a fantasy premise. Kim plays Baek Ho Rang, a wealthy heir who relies on an artificial heart, while Chae portrays Na Bo Bae, a drama writer who develops electrical powers after being struck by lightning as a child. The unusual circumstances bring the characters together and provide the foundation for their developing relationship. Kim said he enjoyed the series whimsical atmosphere and its ability to offer viewers an escape from everyday reality. He has also expressed a desire to continue taking on romantic comedies, noting that their youthful energy and playful storytelling hold a special appeal for him.
