Welcome to Waikiki[1] (Korean으라차차 와이키키; RREurachacha Waikiki) is a 2018 youth South Korean television series starring Kim Jung-hyun, Lee Yi-kyung, and Son Seung-won. It aired on JTBC during Mondays and Tuesdays at 23:00 (KST) time slot from February 5 to April 17, 2018.[2][3]

On June 6, 2018, it was renewed for a second season, which premiered on March 25, 2019.[4][5]


Three very different young men – Dong Goo (Kim Jung Hyun), who dreams of becoming a film director, Joon Ki (Lee Yi Kyung), an eccentric actor who performs to make a living, and Doo Shik (Son Seung Won), 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. They are joined by Dong Goo (Kim Jung Hyun)’s younger sister, Seo Jin (Ko Won Hee), who actually manages the household in Waikiki, single mother Yoon Ah (Jung In Sun), who has made an unexpected entrance at the guest house with her baby, and Dong Goo (Kim Jung Hyun)’s ex-girlfriend Soo Ah (Lee Joo Woo).[6]



A kind-hearted young man but is an "icon of misfortune" who dreams of becoming a movie director. Picking himself up after a painful breakup, he starts working again. He falls for Yoon-ah.
The son of an A-list actor who wants to follow the footsteps of his father but is stuck in minor roles. He is very determined to make it on his own and would go to great lengths in order to land better roles. He is allergic to walnut. He eventually sees Seo-jin as a woman.
A timid freelance writer who barely receives work. He currently works in a convenience store and whiles his time away writing a web story.
A single mother who ends up staying in the guesthouse with her daughter Sol in exchange for helping out. She makes the other residents uncomfortable with her quirky behavior and is prone to forgetting things and causing accidents. She initially wanted to be a rapper but later on studied in earnest to be a pastry chef. Afraid of trusting men again, she eventually agrees to be Dong-gu's girlfriend.
Dong-gu's sister who wants to be a journalist but had difficulty landing a job. Joon-ki calls her Chewbacca, later on shortened to Bacca. Her facial hair is a source of embarrassment and she has to shave it regularly. She falls for and starts a relationship with Joon-ki in but hides it from her disapproving brother.
Dong-gu's ex-girlfriend, a famous model, who suddenly broke up with him. She ends up staying in the guesthouse when her new boyfriend ran away with all her money. She tries to make a comeback with Doo-sik's help.


Pastry chef, owner of bakery, instructor in Yoon-ah's school. In love with Yoon-ah.
