Elf: the Charmander You Got at the Beginning Is Almost Dead.

Others started with three families, but I started with a useless Charmander who was about to die. It was returned three times and no one wanted it. I am an orphan and no one wants me. We got it together. Later I found out that there was a system hidden in my mother's belongings. Later, Charmander learned that its flames were inherently different. Later - the whole Hualan City knew about it.
