Past speculations, originating from online community posts about alleged sightings and social media activities, were re-examined. However, both their agencies have officially denied the rumors, clarifying that the two are merely close friends.

The initial mention of Lee Changsub and Lee Joobin together dates back to a November 2024 online community post. This post claimed a teacher saw them dating in the Maldives, but it was an unverified eyewitness account without photographic or video evidence. In July 2025, another speculative post emerged, citing their SNS activities, yet this also remained an unconfirmed online rumor. Separately, Lee Joobin's perfect ID photo was reportedly misused in illegal sports betting, used car transactions, and investment scams due to its striking appearance.

Bloggers conclude that the dating rumors surrounding Lee Changsub and Lee Joobin are unfounded and have been clarified as mere happenings. In Lee Joobin's case, her exceptional beauty even led to the bizarre incident of her ID photo being exploited for criminal activities, and her on-screen chemistry with Ahn Bo-hyun was also interpreted as professional camaraderie. Lee Changsub has shared his experiences as a trainee, including strict weight management and rigorous evaluation systems, highlighting the challenges faced by idols.
