Actor Koo Ja-Sung shared behind-the-scenes details of the short drama 'Naughty matchmaking'.

Koo Ja-Sung plays the male lead Cha Kang-jun in 'Naughty matchmaking,' which premiered on the short-drama platform Lezin Snack on the 9th, radiating a warm yet deadly charm.

'Naughty matchmaking,' in which Koo Ja-Sung gave a passionate performance, is based on a web novel of the same name and is a romantic drama that begins when Korea University Hospital intern 'Kim Na-eun' (played by Yeoreum) meets legendary surgeon Cha Kang-jun, famous for his prickly personality, at a matchmaking meeting. As of the 20th, 'Naughty matchmaking' ranks No. 1 on Lezin Snack's popularity chart and is running a successful streak at the box office. In response to fans' enthusiastic reactions, Koo Ja-Sung personally revealed behind-the-scenes details of 'Naughty matchmaking' and asked for more interest in the project.

The character Cha Kang-jun, a cold figure to everyone but warm only to intern Kim Na-eun, was a new challenge for Koo Ja-Sung. He said, "(Cha Kang-jun) is not simply a cold, aloof man but someone more tender-hearted and warm than anyone," noting, "rather than trying to appear cold, I focused on the character's inner wounds." To that end, Koo Ja-Sung said, "I concentrated on expressing the awkward sincerity that leaks out through the cracks even though he pretends to be strong on the outside."

Koo Ja-Sung brought the Cha Kang-jun character to life through those efforts. He confessed, "When I first read the script, I thought the sync rate was less than 1%," but added, "now that filming is over, I feel it's about 70% similar. The playful side I show to people close to me resembles the character's traits a lot," showing how he merged into the role.

Koo Ja-Sung cited Cha Kang-jun's subtle psychological shifts in 'Naughty matchmaking' as a viewing highlight. He picks the scene in which Cha Kang-jun feels jealous after seeing Kim Na-eun dining affectionately with a college classmate as the most memorable, saying, "It was very interesting to act the moment of change when a man who had been only cold awkwardly shows jealousy." Koo Ja-Sung explained that "the scene where Cha Kang-jun, known at the hospital for his irritable personality, changes without realizing it while with Kim Na-eun is where you can feel that transformation most intensely." In this way, Koo Ja-Sung's three-dimensional acting, which runs through the work, firmly supports the completeness of 'Naughty matchmaking' and captivates fans.

Through this 'Naughty matchmaking,' Koo Ja-Sung has expanded his activities into short dramas and shown his presence to the public, drawing attention to his future endeavors.
