Can anyone tell me, what really was the deal with salvation spirit (like what was the deal and what the spirit wanted in return)? I am too lazy to reread the chapters.

My guess is it calls itself "spirit of salvation" because it helps humans defy fate by granting them the wishes that fate did not allow, even if changing heir fates ends up causing those humans' deaths, as a result: I imagine it as a kind of automatic auto correct of the universe after a "computer virus" (aka salvation spirit) caused a "computer bug".
Seme is an absolute psychopath. He dug out his father's heart at the last chapter.
WHAT HELLO
Actually they're both perfect for each other. Its wholesome 1on1 romance of two manipulative bastards
He did right though his father jerk off to him also beat him up he has wounds on whole body.
His father is a disgusting piece of trash so dont worry. He deserved it.
