Nah, sadly its still very niche, you can find some comics and art on tumblr and twt probably.
Its basically like hanahaki x omegaverse coming together for a genre, the closest i can recc is a hanahaki manga that also has some ov undertones

Yes, A story (Spring in the Heart) by bbong author of Never Understand, was discontinued due to copyrights issues cause the flower disease is patented under the name Hanahaki by Matsuda Naoko.
Later it was found out that the statement given that the Hanahaki disease is patented was false, the concept was never patented/copyrighted (there's no info saying it is). The possible reason the manhwa got backlash could mainly be that a Korean author was using a Japanese concept. In 2017 there was a lot of tension between the netizens. Lez hin at this time was still at its beginning and most likely didn't want to add to the fuel and listened to readers complaints.
