Ayoung (아영) is a South Korean singer under Cube Entertainment. She was the main vocalist member of the ballad group A Train to Autumn.
After being introduced as a member of A Train to Autumn, together with her band-mates, she recorded the group's pre-debut digital single "A Watercolor of a Rainy Day". Later on, Ayoung officially debuted in the group with their second digital single "That Season You Were In" on November 5, 2018.
Unfortunately, the group presumably disbanded after their profile was removed from Cube's website.
