Reza DA was born in Bandung. He is a graduate of Politeknik LP3I Bandung. However, he spent most of his teenage years in Surabaya, Pekalongan, and Sidoarjo. Reza can speak Javanese little by little.
His childhood was not very pleasant. According to a podcast with Gilang Dirga, Reza admitted that he often got bullied by his school friends. Reza once experienced a dark moment to the point of feeling depressed. To express his feelings, Reza wrote a letter to Allah and poured out his heart about how people were insulting him. He continued to do so until he was in college.
Reza was born with an extra thumb on his left hand. Initially, Reza didn't care about it. However, his thumb became a subject of ridicule for people.
"My thumb is like this, back then in school, it became a subject for them to bully me. Finally, my late grandmother was afraid that when I grew up, I would be ashamed of it, so it was removed and there are still stitches left," said Reza, telling one of his life stories in a podcast with Gilang Dirga on YouTube while showing his thumb.
