I'm not much of a fan reading manhwa as it most of the time disappoint me and the story filled with too much drama that it get's annoying. BUT, There are few exception, such as really good story and characters development. Most of them in this list is which I've re-read multiple times and liking it all over again.
For all BL manhwa/manhua list regardless its bad or good. You can find it here:
