I've heard about The Girl Who Spit Flowers by Naoko Matsuda but I've never read it myself. I'm not sure if it's on mangago either :/

there was a manhwa called "spring in the heart" but its no longer available...i think there arent any cause ive read somewhere that the creator of the "hanakaki desease" sued them cause they used that concept without her approval.
