Manga The Symbiotic Relationship Between a Panther and a Rabbit

I was a rabbit shapeshifter who couldn’t even transform into a human by my coming of age ceremony. My family said that I was just a half and placed me in a basket… “You’re crying? Go on, cry more.” I was then picked up by a black panther with a mean personality. “You’re lacking in stamina. I’ll eat you the day after tomorrow, so keep trying.” This fierce beast. Staring at my trembling face, the black panther’s eyes glistened. “Seems like I just felt thrilled.” Mom, I think he’s crazy! To survive a fairly crazy black panther. “The wild beasts are possessive, no matter what it is.” ….Is it possible?
