Looking for a Book! Maybe a Quick Transmigration Story About a Beloved Cannon-Fodder Character 找书！快穿万人迷炮灰好像

I can't find this book. Please help me out! There's a scene (I think it was set during the apocalypse) where the female lead, who always presents herself as a man, spends a ton of points to buy a bottle of liquor. She goes to confess to Male Lead 1, but he turns her down. She asks him to pay her points back, but he doesn't believe the liquor cost that many points.
