"Hello, this is Antenna.

Last month, an anonymous individual 'A' made a lengthy post on an online community, claiming that an actor 'L', whom she had dated for over 4 years, had recently ghosted her after a single text announcing their breakup. 'A' then made various accusations against 'L', including cheating.

Then, after speculations arose that actor 'L' might be Lee Seo Jin, the original post by 'A' was deleted.
