Gabriel Jenny, Blackpink's mention of identity being revealed is making her look ignorant

In the final episode of Gabriel, a man who was looking closely at Jenny said, "I'm curious about something. I think I've seen you somewhere." Jenny was flustered, but she tried to pretend not to know and said, "I don't know what you're talking about." lol

"I saw your poster in my sister's room. It looks like a group. Are you sure you don't sing?"

He dismissed it by saying he didn't know until the end and just said it was a pretty name.

I really felt like he was a global singer
