you're married to your profesor,it was arranged.... Now you're his student but eventually you were weak in his subject,you worked beyond hard but you can't understand why you always fail? It felt like your answer sheets are being exchanged with the topper,she hated you so it had a chance but whatever....it affected married life of you and Dazai,he constantly enraged on you that you couldn't even get passing marks

"you can't even pass in my subject...just here to ruin my reputation"
