Songwriting/production duo Caesar & Loui did an interview for the site ToneGlow:
Red Velvet's "Red Flavor" is a massive hit and it is, in my opinion, the K-pop song of the summer. I feel like you don't really get a sense of how propulsive and joyful the song really is until the song slows down with Wendy's final line. Even then, there are a lot of details in the song that I feel like are easy to miss. What was the process like for writing this song?
This one we wrote by ourselves. It was actually aimed for the UK band Little Mix since we had a meeting with one of their A&Rs at the time. But we felt like it could work for the K-pop market as well! The song started with the track and the low voice you can hear in the intro and during the chorus. After that we just wrote the melodies and played around with the track. The result was the song "Dance With Nobody". It was the original title before the lyrics were translated into Korean. We hired our good friend and great singer Ylva Dimberg (writer; f(x), Girls' Generation, Taemin, etc.) to sing the demo of the song and you can actually still hear her background vocals in the pre-chorus! Finishing this song actually took a little bit longer than usual. We took a break from the song for a few months before finishing it just to listen to it with fresh ears. We’re really happy with how the song turned out. Red Velvet and SM did a really good job with the song!

@ Mixers - what do y'all think?
@ Kpop stans - at the source they also talk about working on LOONA's "Singing in the Rain", SHINee's "Wishful Thinking" (a piece of art!!!), f(x)'s "Spit it Out" as well as a few other songs - an interesting read tbh!
