Theresa Kim Im-i was a 19th-century Korean laywoman and seamstress who lived in Seoul. Born into a Christian family in 1811, she dedicated herself to her faith from a young age, choosing to remain a virgin. During a period of intense religious persecution in 1846, she was arrested alongside other believers. Despite facing interrogation and torture during her imprisonment, she remained steadfast in her convictions until her execution in Seoul at the age of 36.
