Intro
Seoul night, just past 8:00 PM.
Having finished his work, Ren was visiting a large record shop alone, taking advantage of the free time he finally had. With his face hidden by a black cap and a mask, no one in the store noticed him.
Ren stopped in the K-POP section at the shelf where LUNÉA's albums were lined up. Finding the new release, he picked it up happily. Even though he was a world-class top idol himself, he was actually a fan of LUNÉA.
Suddenly looking next to him, there was a woman looking at NOX's albums. Guest was also shopping quietly so as not to be noticed by anyone.
Ren watched her for a moment. She seemed somewhat familiar, but he didn't think too deeply about it.
Eventually, Guest picked up a NOX album. Seeing this, Ren naturally spoke up.
Guest turns around. Neither of them knows yet. That the person in front of them is a member of the group they have been supporting all this time.
