aoen is a seven-member boy group under YX LABELS. Formed through the reality survival show Oen-High, they made their debut on June 11, 2025 with the single album "The Blue Sun".

 

Their group name is a combination of the purity and possibility represented by "Ao (青; translation: blue)" and the encounters and connections represented by "En (炎; translation: flame)". It holds the meaning of "a passionate run that fills the world with blue, the color of the hottest flame". It symbolizes the world's hottest flame burning inside the group's heart while they work energetically and support everyone.
