Welcome to Waikiki (2018)

Three very different young men - Dong Goo, the bad luck incarnate who dreams of becoming a film director, Joon Ki, an eccentric actor who performs to make a living, and Doo Shik, a freelancer writer who fiddles around doing nothing most of the time - open a guest house named "Waikiki" in Itaewon where many foreigners come to stay. Although they have no clue how to run it, they're eager to earn money to pay for the production of their upcoming film. Joined by Dong Goo's younger sister Seo Jin, who actually manages the household in Waikiki; single mother Yoon Ah, who has made an unexpected landing in the guest house with her mysterious baby; and Dong Goo's ex-girlfriend Soo Ah, they all start living together in an uncomfortable and suspicious atmosphere.
