I read both chapters today and I must say that this is one interesting setup. A perfect manga with message "not everyone is meant to have kids or be a parent".
Not only are his biological parents pieces of s**t, but his adoptive mother and stepfather as well. I mean, just look at the facts:
-adopts the kid with her then husband, then files for divorce.
-marries another men and has a biological daughter with him, then proceeds to totally ignore the kid she adopted as a son becasue she is trash.
-her new husband literally kicks the boy out of the house because he sees him as a "rival" to his new family. And mom agrees like the lowlife she is.
-dad and mom file for divorce and make their daughter miserable as well. Killing the entire point of kicking the boy out in the 1st place.
These people are so evil and incompetent as human beings it is shocking. Where are Asamura Taichi and Akkiko Ayase to show them how it is done? If you know these two then we can be friends.
Anyway, I am looking forward to future chapters where the kid becomes a man and protects the person that is dear to him from trash people like these two adults only in age people.
