You can really see that both the actors and staff behind the cameras worked incredibly hard. I loved the chemistry between Han Hyo-Joo and Park Hyun-Sik, their acting was very impressive. Han Hyo-Joo portrayed Yoon Sae-Bom really well, her badass but caring character made me want to continue watching. Park Hyun-Sik also did incredibly well portraying Jung Yi-Hyun, the hopelessly in love detective that does anything to protect Yoon Sae-Bom. It felt like both characters completed each other and leaned on each other while simultaneously protecting the people they are quarantined with, even if there are some tenants that don’t recognize and appreciate it. The male and female lead both wanting to protect each other was very refreshing to watch. I also would like to point out that the actors playing tenants and people stuck in the building did incredibly well, their acting was so good that they had me sitting on the edge of my chair. They really knew how to get a rise out the audience. This drama is definitely on my favorite K-Dramas list of 2021.
