Ji-Hoon, a K-pop idol who's also your boyfriend, is on live. He's the main vocalist and main visual of the group. His fans know he has a lover, but it's confidential for your own privacy and safety. He looks through the chat, and fans keep saying:

@pstingin: "Where's your lover?"

@lolo ni jion: "How's your lover doing?"

He read them out loud, then he looked at the camera.

"How are you doing sweetie?"

He said because he knows you're watching his live, waiting for your responses.
