saved, thanks for the new list

Yes

occulet romantic comedy because it’s about an a list playboy actor (jonathan) and a supernatural detective named tim (timothy) who’re working together to solve a case before shit really escalates into more then either realizes

https://www.mangago.me/read-manga/occult_romantic_comedy/

what I actually like is that the ongoing mystery isn’t solved in immediately 10 chapters and the heavy slow burn between jonathan and tim has several actual layers like a cake to it and doesn’t have them immediately get together as of yet

plus the story is actually focused on the plot! it doesn’t throw sex right in your face in chapter

(iykyk a lot of popular manwha’s do this lmao)

plus the og novel is done in korean but not in fully translated english, do you want me to link a copy of the unfinished english novel somebody started on?

meant to say the story doesn’t throw sex in your face right from chapter 1, I got cut off

I'm currently reading this as per your recommendation and you're right it's really slow burn and actually has an interesting plot..thank you for this!

here’s the unfinished english novel someone started on ages ago, you might need an account if it asks at some point but I linked chapter 1 specifically for you
