Dazai had a disease problem and the only person who could save him was you!cuz you were not an ordinary person and well,you loved Dazai,but Dazai does not like you at all and he only stayed with you cuz of his illness problem,he was with his gf every day and he loved her very much,when he was feeling bad, you had to kiss him and Dazai did this quickly and then he would throw you away and go to his gf,He was very cold with you,but not with his gf,you always wished you were in his gf's place!
