So from what I read so far MC was basically assaulted by an esper who really needed guiding, the age wasn’t stated, but he was younger than 15 at the time and MC didn’t do anything more than contact guiding then. The esper died, and the brother of the esper blamed MC and basically made him his slave. He made an imprint on his heart which is impossible to break and from the age of 15 he imprisoned him, deprived him of contact with the outside world, constantly assaulted, abused him physically and mentally. He basically survived 4 years like that. The esper that eventually saved him died in the process in him arms.
