Hanahaki Disease is a disease where the victim suffers from unrequited or one-sided love. The victim will grow flowers inside their lungs and heart and eventually die from the disease if the person they love doesn’t love them back. It can be cured if the other party confesses their love back or through surgical removal, which will not allow the victim to love again..

You are suffering from this disease..but the person you love definitely doesn’t love you back. He’s your bully after all..
