After Thi's mother died, her father was unable to raise her, so she lived with her aunt-in-law and grandmother. Thi's grandmother left her a ring when she died. While packing her things, Mrs. Mai discovered it and scolded Thi, causing her to run away from home. Thi wandered around and met a group of children, whose family adopted her. Since Thi left, Mrs. Mai felt remorse and searched everywhere. When Mrs. Mai found out where Thi lived, she came to pick her up.
