I don't know how to feel about the MC. He went through a lot of stuff in the past, was nearly killed by that woman when he was a kid(I am gonna assume that he was gonna get killed because -90 means wanting to kill someone). His childhood sucks and its not shocking to see him like this. But 
treating their feelings like that is a dick move. 
And on that note, what happens to Sakura's real body after she possess's someone? Does the body become a dead body or the the owners interchange?
