So for her concept in her debut as soloist (Birthday is her debut song), somi trying to bring a concept where it can be between childish yet also kinda like someone who gonna enter adulthood, i mean she's still a teen so it suits her age. Not too childish not too adult-like. Before she become a soloist, she was a member in a temporary girlgroup from a famous idol audition in korea called Produce 101,she become recognizable thanks to that show. And the girlgroup name was I.O.I, you can check it out too, though it already disbanded not too long ago. Sorry for my bad english
Love your reaction ^^ somi B-side is called Outta My Head and she wrote and composed that song all by herself it's totally different concept from her song Birthday and the song is Amazingggg u will love it u can listen to it on Spotify or on iTunes too since the song doesn't hve MV 😊
