I'm a little desperate because I want to reread this story, but I can't find it :(( I clearly remember that it is a train to busan based story seulrene version, or if not, it's a zombie apocalypse themed story? Seulgi is a photographer and she kept taking photos while they're trying to escape the zombie encounters, and I forgot what Irene does.    Thank you! 🙇🏻‍♀️

im posting this because im really desperate HUHU all i remember from the story is that seulgi disappears when they have music shows (?) then irene notices. she finds out seulgi is sleeping around with girl idols and then when she confronts her about it, seulgi says she helps other idols explore safely or something. then she proceeds to help out irene too because seulgi thought irene was curious as well JFKDJFKSLDJ I really want to reread it but for the life of me i couldn't remember the title
