JYJ's Junsu, currently carrying out his military service duties as a social worker, was spotted in a recent advertisement CF promoting proper protection against ransomware damage.
In the CF, Junsu starts out texting lovely messages to a 'some' woman, asking her, "Are you sleeping?", "Did you eat dinner?", "Did you eat?", to which she responds, "No, what about you?". The woman's name is saved as 'Ransom girl'. The ad then lays out the correct steps to prevent ransomware damage, comparing malicious ransomware to the woman who delivers harmful, unknown items to Junsu, asks to borrow his items forcefully, gets in the way of Junsu attempting to update his software, and more.
