Basically Seulgi was famous, Irene a regular citizen, her bestfriend was Wendy who was a big fan of Seulgi, I remember that they both know each other in a convenience store (at first, Irene was not interested when Wendy talked how she loves Seulgi). Something to add I think Irene was working in that convenience store and the first time Seulgi defended her of a drunk man, but I'm not really sure, if you know a fic with just that description of before it's ok

What I remember is that Irene and Krystal are best friends and it's like Krystal hate so much Seulgi, for that reason she is against the friendship or more between Seulgi and Irene, also because Seulgi is not popular. At the end, all it's because Krystal is in love of Seulgi. I'm looking for this fic, I searched and I can't find, I remember it was very well-known but I can't find it help me pls :(
