Kaminari has the Hanahaki Disease because he thinks Shinso doesn't love him. Shinso has the Hanahaki Disease because he thinks he isn't good enough for Kaminari's love.

Hanahaki disease is a fictional sickness where the victim coughs up flower petals when they suffer from one-sided love. It ends when the loved one returns their feelings (romantic love only, a strong friendship is not enough unfortunately), or when the victim dies. It can be cured through a surgery that removes it, but when the infection is removed, the victim's romantic feelings for their love also disappear. Shinso is in love with Kaminari, a loud yellow haired blonde boy. He hasn't told anyone about the disease besides his closest friends and his sister. Until one by one his family and his crush start finding out. He refuses to get the surgery to fix it. But when the disease gets worse will he get the surgery to save himself or die over one boy? This is my head cannon where Shinso is in class 1-A and him and Eri were adopted by Aizawa and Present Mic who are married This will have an oc her name is Akasuki Hiribashi The disease only gives you a year in this au and you cough up your love interests favorite flower, and you better pray it's not roses. Those things hurt since the stems come up too. The dorm room act is not in effect yet so they all still live at home I don't own any of these characters besides my oc, they all belong to the writers of bnha
