Baek Sung Chul plays the role of Santa, Koo Kyung Yi’s (Lee Young Ae) sole trusted colleague and assistant. Unlike his innocent looks, Santa is a witty, competent assistant who actively aids Koo Kyung Yi’s investigations.
Before becoming Koo Kyung Yi’s assistant, he kept an eye on her, disguised as one of the cleaning staff. Santa is a unique character who uses an AI interface to talk to people, making viewers think he couldn’t speak. But in Ko Kyung Yi’s absence, he goes, “It’s just as I thought.”
In the fourth episode, Santa is seen chasing Kei (Kim Hye Jun) after she breaks into the office of Koo Kyung Yi’s team, and Kei is taken aback as he shows his wit and persistence during their chase. Plus, his witnessing Kei’s gender and her injured leg is expected to provide crucial clues to their investigation.
Santa’s mysterious yet adorable personality is making viewers curious about his identity, especially after revealing his masculine charms in this past episode.
Inspector Koo is available to watch on Netflix.
