Honestly they don’t get together for awhile after the car scene. Also no dirty things happened in the novel in the car scene. Months later they both realize their feelings for one another they ask each other out. You’d have to read it, the novel and manhwa are really different. I love the novel but they definitely drawled out them getting together. But in this manhwa it feels like their moving to fast idk anymore

As someone who read the novel before this makes absolutely no sense in the novel they get together before they do it
