This is really a sad new, Fluttering Feelings is the best Yuri manhwa I have ever read, much better more than others (Pulse, WDSF, etc.) It's one of my favorite, I read it all over again multiple times. Ever since I heard that she got a cancer, I always kept hoping that someday she recovered from a cancer and could be able to draw something with her passionately heart and could able to finish the story of Fluttering Feelings. To think that a cancer took everything away from her, it's really sadden.
May she rest in piece.
