This is the first time BTS's Suga and PSY have worked together on a song. The song is off PSY's 9th studio album, which was released on Friday. Psy 9th has worked with various celebrities, including Hwa Sa of MAMAMOO on a cover of Jermaine Jackson and Pia Zadora's 1984 hit When the Rain Begins to Fall and Crush on Happier.

He discussed the song on the April 30 edition of Knowing Bros (Ask Us Anything).

According to Soompi, PSY said, "One day, I received a text message from an unknown number." 'Hello, this is Suga,' it said. I'd want to discuss things with you.' So we got together. Of course, (Suga) is a fantastic performer, but he's also a fantastic composer. He's already produced songs for IU and Heize. So he'd previously created a number of songs for other people, and he told me he wanted to round off his producing effort by giving me a song.”

"That's when he brought me the guitar for the song" (That That). Suga is the one who made the rhythm. 'Could you possibly sing this song?' he questioned. 'It doesn't even have to be this,' I added. What song would I refuse to perform [if you created it]? 'I'm all in!' So we kept talking back and forth like this while working on the song, and he ended up featuring on it. "I'd want to use this chance to show my appreciation to him," he continued.

PSY has spoken about Suga before the song's release. "I don't want to make younger artists feel awkward when we meet. I don't want to be a difficult person to approach. He is not only not my business junior, but he also feels like a buddy. It was difficult to discern any age difference. That's fantastic if he considers me a bestie "He was cited as saying by the news agency ANI.
