QuoteDisplay MoreOn January 12, RBW Entertainment revealed the two ONEUS members will be taking a hiatus to recover for health reasons. The label stated, "Leedo was diagnosed with skin inflammation on the soles of his feet, and he was advised to be careful with his daily activities," adding that he'll be taking a week off to recover.
RBW added, "Xion slightly strained his knee coming down the stairs, and he's wearing a knee brace... On January 5, a medical professional advised he take it easy for 1 to 2 weeks, so he'll be taking a break for awhile so he won't strain himself."

Wishing them a safe recovery!
