Y'know I never really like it when a pet refreshes with a stray and the owner kills the stray. Imo part of the fun of "abandoned" stories is watching the relationship between the former pet and the stray inevitably deteriorate
Typical story: pet yu got f*cked with stray/ wild yu and have kids. They're all dead. End. This type needs good artists since readers enjoy torture scene with nice facial expression, especially kos.
