On the July 20 broadcast of JTBC's 'Sea of Hope', Lee Ji Ah, Lee Dong Wook, SHINee's Onew, Kim Go Eun, and AKMU's Suhyun struggled to fill in the vacancy of Yoon Jong Shin, who had left for a business trip. To help fill in the empty spot, BLACKPINK's Rosé appeared as a part-time worker and delivered healing to viewers through her service and amazing performances. 

With music flowing amidst the warm sunshine and glistening sea, the cast members energetically conducted their daytime operations at the 'seaside bar'. Then, AKMU's Suhyun sat down to perform a cover of SSAK3's "Beach Again", followed by Onew shifting the mood with his cover of Na Yoon Kwon's "Expectation". After Suhyun and Onew's duet cover of "Doll's Dream", Rosé finished the stage with her cover of the late singer Yoo Jae Ha's song "Because I Love You". Rosé brought many to tears with her deep, rich vocals, and showed her close interaction with listeners through her music.

Rosé expressed her thoughts on her performance by saying, "I came here just now to sing, but when I carefully listened to the lyrics, I somehow thought of my parents. I felt a love that was solely for me, and I teared up without even realizing it. On a normal basis, I don't think I expressed my emotions well, but when I listen to these kinds of songs, I think I start to understand my parents' love better."

Everyone was able to enjoy music and the beautiful sea together, through this broadcast. Each person had a different story, but everyone enjoyed the moment with a shared heart.
