The Dark Priest's Dog-Licking Diary

My name is Li He, and I deserve death because—— I've been coveting my sister-in-law, my brother's girlfriend, Daisy. I have lived in the shadow of my brother since I was a child. My brother is tall and I am thin, my brother is brave and I love to cry, so it is expected that I will lose to him in love. Unfortunately, I underestimated my self-control. I began to follow Daisy crazily, send gifts anonymously, and dig out her collection of scrap manuscripts from the trash can... He even spied on their dates at night, masochistically eavesdropping on their flirting and kissing. Brother and Daisy are both knights, living and dying together on the front line. I knew I had no chance, so when they announced their engagement, I cried while sewing a perfect wedding dress to send to the front line. But before the wedding dress could be sent out, Daisy returned to her hometown and brought back news of her brother's death. I looked at the lost Daisy, and a dark thought came to my mind—— My chance has come. I leaned close to Daisy, rubbed her palm, and begged her to think of me as her brother. I thought I would be beaten and scolded by Daisy, but she just grabbed my chin and sneered: "You look a lot like him." In this way, my plan succeeded, but she never loved me. But so what? It's enough that I love her.
