Song Ye Bin, formerly known as Haea, is a South Korean singer, dancer, actress and former member of LIPBUBBLE (립버블). She graduated from Hanlim Entertainment Arts High School and later attended the Musical program at Dongguk University but is on a leave-of-absence. She made her debut in March 2017 (using the stage name Haea) as LIPBUBBLE's main vocalist with their first single, "Popcorn". Unfortunately, the group faced multiple lineup changes and their agency, No. 1 Media (넘버원 미디어; previously known as Zenith Media Contents) could not find enough activities for them to promote. She decided to leave in May 2018. She then moved to Deep Studio Entertainment (딥 스튜디오 엔터테인먼트) and became part of their new idol group, YOURS (유얼스). Their first pre-debut single, “My Memory Is Yours“, was released in October 2020. However, they had a unique concept with fans voting for their top-7 everyday and the first 7 trainees to hit 1,000,000 votes were rewarded by debuting. Unfortunately, the lineup changed constantly and even included male and female trainees in a confusing system. She left in early 2021 without ever re-debuting. In 2022, she switched to acting and signed with Dear Entertainment (친애하는 엔터테인먼트).
