Yuri realizes his feelings towards his friend, Victor. But he decides to keep it a secret. He suddenly feels a bit uncomfortable as his throat suddenly acts weird. He then went to the bathroom and as he thought that puke is going to go out from his mouth, it was petals instead. He then found out that he has the Hanahaki Disease, a disease where the victim of unrequited or one-sided love begins to vomit or cough up the petals and flowers of a flowering plant growing in their lungs, which will, in the end, develop adequately huge to deliver breathing unimaginable whenever left untreated. The only thing that the disease will go away is when the person you like will like you back.
What will Yuri do? Will he confess his feelings towards Victor or he’ll just let the flowers grow in his lungs and die?
