In relation to her participation in the album, Ye Eun has said, “The people who bought the album would know, but you see the weird English that’s beside my name, right? That’s my alias. Ye Eun and Yenny are my names as a singer, but I wanted a name as a producer so after giving it a lot of thought, I chose ‘heartfelt’. The word meaning sincere and from the heart came to mind.”
In addition, she explained, “However, there was some opinion saying that it was too feminine, so producer Park Jin Young suggested that I change the way I write it – according to the phonetic transcription. In American English, it was written Ha:rtfelt, and in the British English, it was Ha:tfelt. Since in America, Hot is pronounced Ha:t, Ha:t contains the double meaning of HEART and HOT!”
She also requested future anticipation with, “Therefore, I chose the name ‘Ha:tfelt’, containing the original meaning sincerity as well as the alternate definitions meaning passion and hotness. You can just pronounce it comfortably as Heartfelt! It’s a name you guys will be seeing from time to time.”
