Everyone Thought This X Account Was WJSN’s Dayoung—But It Was Another Dayoung

Imagine turning up for a celebrity account and finding a stranger with exactly the same name. Fans were surprised, and the account owner seemed even more taken aback. The star of this story is simply a shared name.

On October 21–22, posts on X sparked a mix-up over an account associated with the name Dayoung. Several original X links were shared in a Korean community discussion, including a message in which the account owner explained that they were not Dayoung of the K-pop group WJSN. The mistaken assumption became an online joke of its own.

The appeal is not merely that two people share a name: it is how quickly a name can become a presumed identity online. On October 22, Korean community users shared a cluster of related X links, while a public repost index also displayed the account owner's clarification. No verified data establishes account growth or the views of the entire fandom.

The visible posts and community discussion treat the mistaken celebrity identification as the joke. These are individual reactions, however: they do not prove that everyone made the same mistake or that the singer was involved.

Namesakes are common offline too, but social media puts account names directly in the path of fans' expectations. Checking the profile, the author and any genuine signs of verification helps keep a funny mix-up from becoming an unfair assumption.

A Korean community post dated October 22, 2026, at 3:36 a.m. KST links five X posts from the account and other users. A separate public repost index also displays a clarification that the owner is not the WJSN member. The person's legal identity or residence has not been independently established and is not asserted here.

What is established so far is the namesake account and the reactions around it. No separate comment from WJSN's Dayoung about the mix-up has been verified.
