AKMU appeared on KBS2's music talk show 'The Seasons - Sung Si-kyung's Ear Boyfriend' and performed their new song 'Paradise of Rumors.' Before the stage, Lee Su-hyun encouraged the audience to dance together, saying, "Let's all bloom together," and Lee Chan-hyuk introduced the song as "a song that invites you to the place where a blossomed flower has bloomed."

During the broadcast, Lee Su-hyun shared her experience of walking the Santiago pilgrimage route. She explained, "My dad went on a month-long pilgrimage and said, 'Su-hyun, I hope you go.' I kept postponing it, but when I decided I had to do something, it was the first thing that came to mind," revealing why she went on the pilgrimage with a friend. Lee Su-hyun said, "After returning, I suffered severe plantar fasciitis, and at the time, I was quite heavy, so it was hard to endure." She added, "It was very tough, but through that experience, I realized how bad my physical condition was. My feet felt like they were going to break, and I realized it was because of me."

Lee Chan-hyuk explained, "When this song first came out, Su-hyun went on the Santiago pilgrimage to overcome her difficulties." Lee Su-hyun said, "There aren't many things I can brag about to my brother in life, but I thought I could boast about having walked that path once." Lee Chan-hyuk shared the reason he suggested going on the pilgrimage again, saying, "'Aren't you curious how much better your body has gotten compared to then?'"

Sung Si-kyung mentioned that he recently lost 10kg and empathized with Lee Su-hyun, saying, "You worked hard. We're diet buddies." Lee Su-hyun revealed that living with her brother has many inconveniences, but despite that, it is a precious time. On this day, AKMU taught Sung Si-kyung the key dance moves of their new song and performed on stage. The broadcast aired at 11:10 PM that day.
