On September 20, 2026, OurUHK published “#OurUhk Support 260920 99umoong Go Find IU,” sharing a fan account connected to IU’s theater stage greeting.
The post says that fan 99umoong had IU wear a support item and received verification photos, while also sending IU an 18th debut-anniversary greeting.
This is a Hong Kong fan-support repost, not an official announcement from IU or EDAM. The original asks re-posters to credit OurUHK.
