Kim Jeong Hwan, better known by his stage name Yo Han, was a South Korean singer and a member of boy group Top Secret (now known as TST). He made his debut alongside bandmates Ain and K in 2013 as vocalist and dancer of the group NOM (No Other Man). After two of the original members left in 2014, the group continued to experience difficulties to promote and finally disbanded in 2016. In 2017, he became the vocalist and dancer of Top Secret, later rebranded as TST, and debuted with the mini album "Time's Up". The group enjoyed moderate success but was hit with the Kyeongha scandal and later departure from the group and Wooyoung's health issues. He ran a YouTube channel with Ain called "YO-I" but sadly, Yohan was found dead on June 16, 2020 and the family requested the cause of death to be omitted from the reports so it has never been revealed.
