i fear its going to be a bit of a stretch since theres honestly not much plot djhcbdh
slut - valencia grace, simply because of hyunibini's line of work in this and how people might view it (i also wanted to rec this song so bad cause i love it so much)
stunner - ten, since hyunjin's beauty is kind of the whole thing that inspired this fic (you'll see, it'll make sense), but also generally suits how changbin is as a lover with him :3
i love this question though, it unfortunately fell on the most plot-less fic / the one fic i dont have songs for so i had to look for them, but pls dont hesitate to ask this question for other wips in the future if you feel like it hehehe <3
