Just hours before the final episode of JTBC's 'Welcome to Waikiki' aired, Jung In Sun admitted that she has been dating co-star Lee Yi Kyung for approximately a year, surprising viewers with the news. 

Jung In Sun said about her newly public relationship, "Before ['Waikiki'], we went on dates comfortably. If the news had come up back then, there would not have been this much public attention, so I believe it is due to the viewers' love for 'Welcome to Waikiki'."

She continued, "We started the production knowing that we would have different love interests. We wanted to draw the line, up until the last episode. The other actors didn't know. They knew that I had a boyfriend, but not who the boyfriend was. When they heard about it later, everyone encouraged me. I felt even more apologetic... It's true that I will still need to be careful in regard to future productions. Again, I'm sorry toward the 'Waikiki' staff members. I do feel a little burdened by the dating news blowing out now, but because it's a matter I must take responsibility for, I can't just focus on my burdened feelings."

Meanwhile, many viewers enjoyed watching 'Welcome to Waikiki' for its relatable appeal and comedy.
