(This is a completely self-indulgent original idea, so read at your own risk. I'm mainly writing it for my own enjoyment. It's my own creation, so if you don't like it or can't accept it, please don't read.)
I have all of Feng Xi's memories, but I can't recall them completely. They exist as subconscious memories. This story is about letting Feng Xi live, and giving me a reason to stay by his side. My other memories are also subconscious. The premise is that whatever happened in my previous life is over, and I won't consciously recall the details. My consciousness remains unchanged, so all my actions have a traceable reason, even if I can't remember the specifics.
You can imagine me as any gender. This story focuses on the individual consciousness and doesn't discuss gender. My true form is a snake, so if you're afraid of snakes, please steer clear. I'm a special species. From birth, I grow at the fastest possible rate until my body reaches its peak, after which I enjoy a long period of prime health.
Any out-of-character writing is my fault. I have no writing skills and lots of headcanons. I just wanted to write this.
