Merman

The Beast Nation sent our royal family two beast slaves as a token of goodwill after they were defeated. My concubine-born younger sister took the tall and upstanding white tiger with piercing eyes, leaving me and the dying merman to look at each other. In my previous life, I took the merman as my personal bodyguard and trained him out of compassion. I spent a fortune to treat his injuries, and I even bought his slave contract at the price of ten cities and set him free. He also took great care of me, staying by my side day and night. I thought we were both in love, so I turned down dozens of marriages and stood by him with all my heart despite everyone's loud disapproval. However, when the beasts attacked again and threw my sister and me into the surging river, I frantically pleaded with the merman to save me, only to be violently slammed under the water by his massive tail. I watched helplessly as he carried my sister away. I realized at that moment that he had only given himself to me to save his own life. He had remained loyal to me even after regaining his freedom because he wanted to see my younger sister. I struggled in the filthy river, eventually suffocating as my lungs filled with mud and sand. When I reopened my eyes, I was transported back to the day of the beast slave selection. Looking at the dying merman, I covered my nose and taunted, "Where did this dead fish come from? It reeks!"
