Okay I don't know about this manhwa/manga ....but if you are willing to spend time looking for this one I got a tip for ya
tap any of the tags you will end up at a page were the series have that tag ....you will see search tags tab.... Search keywords related to the manga you are looking for eg. Actor BL, Actors x fans , Red fate string .... disclaimer this might not work 100% if the one you are looking for has less views/tags then the chances are very very low and yoh will be wasting your time.....you can do the same looking into different lists and leaving comments there
I have a feeling that I have read something similar to your discription....but I really do not remember any names as of now....
Hi does anyone know the name of this bl where the uke sees red strings and it connects to a guy whose an actor/model? Something like that,,, forgot the name ╥﹏╥
