On the August 3 broadcast of JTBC's 'Sea of Hope', the cast and crew spent their last day on the beaches of Pohang, before moving on to a new city. 

The crew then bid farewell to their first guest and part-time worker, BLACKPINK's Rosé, and also spent a day cleaning the beach after closing their pop-up restaurant/bar. 

The preview for next week's episode, set to air on August 10, showed a new musical guest joining the crew on the beachside bar in Gosung. Musician Sunwoo Junga was seen joining the 'Sea of Hope' band, performing solo songs as well as a duet with SHINee's Onew. 

In particular, viewers were moved to see Onew and Sunwoo Junga singing a duet version of SHINee's "Selene 6.23", a song written and composed by the late Jonghyun. Onew was also seen possibly tearing up after performing the meaningful song in front of an intimate audience, as he remarked, "Just a moment... I think I could cry."

Numerous fans were moved to see Onew showing his emotions, and hashtags including #SHINee, #Onew, #Jonghyun, and #Selene6.23 were seen trending on Twitter.

Are you looking forward to hearing a duet version of SHINee's "Selene 6.23" performed by Onew and Sunwoo Junga?
