Song Byeong-hwa, known professionally as Song I-han, is a South Korean singer-songwriter. He competed in the blind audition program Blind Musician in 2018 and won the competition, immediately releasing his debut single "Reason". At the end of 2020, he released a special single entitled "I Will Be Your Shining Star" amidst the global COVID-19 pandemic. The ballad rose in prominence and was nicknamed "wedding song icon" upon the launch of a contest in which three soon-to-be-married couples would be selected for a free performance by Song at their wedding. Song received two award nominations at the 36th Golden Disc Awards.
