On March 20 episode of JTBC's talk show 'Knowing Brothers', Hyeri and ROSÉ made a guest appearance.

Hyeri continued, "The most touching surprise gift that I received from ROSÉ was the time when she was on a concert tour outside of Korea."
She carried on, "She texted me on my birthday, and we exchanged text messages. Right then, the doorbell to my house rang and a large flower bouquet was delivered to me. It turned out the bouquet was sent from ROSÉ. My heart almost melted then."
She added, "I never told ROSÉ my home address though. I don't really invite friends to my house, because I live with my family. So, I was even more surprised because of that."

ROSÉ said, "After I planned to surprise Hyeri on her birthday, I was like, 'How I am going to figure out her address without asking her?' I thought about it for ages."
She resumed, "Then, I remembered meeting Hyeri's sister. I looked up for Hyeri's sister on Instagram, then told her my plan via direct message and asked if she could tell me their home address. I was so happy when I got it."
Hyeri commented, "Isn't ROSÉ impressive, guys? She's truly amazing."
