hm.... excellent question, i'm extremely only sukufushi, so any trope of theirs i end up reading! I like anything with them because everything, incredibly, goes with them! But, my favorite for sure is enemies/hater to lovers, it's my biggest passion, there's also wedded bliss and second chance (although I don't remember reading one like that this year - so sad), can I consider age gap a trope? If so, I think that would be in first place... But in general I think that's it, if it's sukufushi, I'll read it all (with a few exceptions).
