Shin In Sun is a South Korean singer and musical actor. He graduated from Gwangyeong High School and later obtained a bachelor's degree in Acting from the Seoul Institute of the Arts. He debuted in 2017 with a minor role in the musical "Battle of Haengju" and got his first major role in 2020 in the musical "Mozart". Most of his family members are involved in politics but he always wanted to perform on stage. His major break came when he auditioned for "Mr. Trot" and reached the final rounds managing to end up in 9th place. This has allowed him to earn some popularity as he now is more focused on singing than in theater. (Source: Korean = NamuWiki) Watch drama online for free.
