My favorite it's really good and sad, I chose to ignore the explanation because I like sad stories so to me they haven't met in this lifetime but who knows maybe they'll meet again.
i feel like this 12 chapters story is equivalent to 1 volume standard BL manga. Author can even do a physical copy of the manhwa if they want to. but i guess if you want to compare to normal length (40+ chapters) manhwa, then it is relatively short I guess. Anyway, my thought on this. Its "short", sweet and wholesome and shounen ai. suitable for re-read material.
