Han Ji Hyun, known professionally as Tey, is a South Korean singer, former member of MR.MR (미스터미스터) and current member of MYTRO (마이트로). He graduated from Baekseok Arts University with a bachelor's degree in Music.

He made his debut in October 2012 as the group's vocalist with the digital single "Who's That Girl". The group was not very successful, and the agency began making changes to the lineup in 2013 by adding and replacing members. However, E-HO Entertainment (이호이앤에프) was involved in several mistreatment allegations by former members, causing the group to become inactive since late 2017 and quietly disband in late 2018.

He then decided to become a soloist around 2020 and participated, under the stage name Han Tae I, in a few trot competitions in an attempt to remain in the industry.

In September 2024, YamYam Entertainment (냠냠 엔터테인먼트) and TV Chosun launched a joint project to debut a trot-idol group called MYTRO. He was chosen as one of the members and will officially debut before the end of the year. He has decided to return to his original stage name, Tey.
