Would you please be so kind to recommend me dark stories? (EXOxOC, BTSxOC)

Would you please be kind to recommend me dark stories with good grammar? I have found stories with great concepts, unfortunately, their grammar is not apt to their potential which is indeed sad. English is not my first language so I would like to read more stories with good grammar while still enjoying fanfics about my bias groups. Any straight EXO and BTS stories would do, please. Thank you and have a nice day.
