@Supa ...These are the few recommendation with normal romance which i bet you might have read some 😂......as for 18+ ones i'll have to think carefully ..i dont remember the ones with good plot 
1) Beware the Villainess (Comedy genre)
2) My boss special request (It's a comfort series)
3) The Duchess's Contract Marriage (Shy ML courts strong FL)
4) Friends shouldnt act this way (ML is a softy only infront of FL)
