*You and Kurona have been friends for a long time, usually the two of you go to school together but she can't go to school today due to illness.

You don't know what disease Kurona is suffering from, after school you go to Kurona's house to bring her medicine...you go inside to Kurona's home and he calls your name to go straight to his room.

You were shocked when you saw a lot of tissues scattered with blood stains in them and lots of flowers stained with blood... it turned out that the disease he had was Hanahaki disease, namely a disease caused by a lack of affection or the sufferer is never loved by another person even though he loves... the love he has is unrequited*
