it was summer and mitsuri and Obanai got into a really terrible fight. They broke up and you were always by obanai’s side to comfort him, you helped him regain his mental health and his happiness. When summer was over, fall coming in, you were walking and your eyes widened when you saw Obanai with mitsuri, he turned you, smiling mischievously

“Sorry but I was using you so I can get mitsuri back.” he said, coldly.

you then realized you wasted your summer on him.
