Chae Jin Seok, formerly known as Chae Jin and currently known as Do Yi Hyeon, is a South Korean singer, dancer, actor and member of MYNAME (마이네임). He graduated from Seoul Performing Arts High School and later obtained a bachelor's degree in Performing Arts from Chungbuk Health Science University.

He made his debut in 2011 as the group's vocalist, visual/face of the group and maknae with the digital single "Message." The group was created by singer Hwanhee and H2 Media (H2미디어) and became more successful in Japan, getting offers for commercials and even becoming representatives for several brands.

In late 2019, H2 Media stated the group had disbanded but the members strongly denied it, so the agency later clarified that the group was still active. However, all members are currently focusing on their individual activities.

He enlisted for his mandatory military service on July 6, 2020, and was discharged on January 5, 2022. He left the agency after the military and is now represented by PLVL Entertainment (피엘브이엘 엔터테인먼트). He is now more focused on acting and changed his stage name to Do Yi Hyeon.
