The members of 'I Live Alone' traveled to Jeju Island for the show's 4th anniversary; however, Yoon Hyun Min could not attend due to other filming schedules. Instead, he made an appearance with a phone call. 

On the phone, Jun Hyun Moo asked Yoon Hyun Min what he'd want to do on beautiful Jeju Island. Yoon Hyun Min answered, "I want to do some lovey dovey stuff like writing on the sand."

Jun Hyun Moo poked fun and asked, "Who would you like to do that with?" He tried to avoid answering by abruptly saying, "I hope you guys have a good time." 

However, Jeon Hyun Moo continued to mention Yoon Hyun Min's celebrity his girlfriend. He asked, "What do you call Baek Jin Hee?" Yoon Hyun Min answered, "Ye-ppeun-e (Beautiful)", and also revealed that Baek Jin Hee just calls him 'Oppa'.

Last month, the celebrity couple finally admitted they were dating after multiple denials.
