Copywriting:
A famous treacherous son among the nobility.
Going back to the past does not mean changing the future first, but many problems left over from history are waiting for him...
Family, friends, relatives, and even rivals, Sirius owed them too much.
They have the same name, or even the same person, but when they come back, it is destined that they cannot have the same existence in time and space.
Therefore, his identity now is [his] son.
It's funny, isn't it? Be your own son.
Looking at his former self, Sirius smiled silently.
"This is what I should do. The debt left by my father should be repaid by my son, and the Black family cannot withstand another blow."
"No need, he... Already has Harry's godson, so my existence is unnecessary."
