An Ageless Person Coming Back (DISCONTINUED)

...TBH I have nothing to say for this book so you better read to find out!
Also, the reader is male, and MC (Yuu) is non-binary.
Edit: Reader is kind of like a main-side character

See ya in the book, dear readers~
*Disclaimers: Spoilers, pictures are not mine unless I say so.*
Edit: By the progress so far, the majority of the drawings in pen or pencils are mine.

All the details will be written on the Author's Note and Choosing Reader's Appearances
