Eunji's management company, Play M Entertainment, filed a complaint against the alleged stalker, accusing him of violating minor offense laws, among other things. Despite their repeated requests for him to stay away from their artist, he stalked her and even went to her house without permission. They have decided to take severe legal action against him because he has been causing significant harm to Eunji.

Play M Entertainment has also stated that it is looking into malicious commenters. Some of them have already been charged, and they will continue to fight for the rights of their artists.
