please speed i need this

does anyone have any bl/yaoi recommendations for someone who's never rlly read yaoi before? I want my friend to get into the genre but theyre lowkey on edge bc their other friend recommended them bj alex(like oml why did they recc that) and they said it was too much/bad(valid). They said if my recc isnt good, they'll never try reading yaoi again. i lowkey dont know what to recc bc it's been a while since ive read a good one. They want plot and like mystery and really doesn't want the first chapter to start off with the mcs fucking so I assume shes ok if its just shounen ai.
