Exactly, i thought i was the only one who felt that, the girl pissed me off i really don't like her i wish she wasn't in the manga she seems so full of herself ugh
for two reasons:
1) he doesn't want to disclose to anyone that he has psychic powers because that would only be a burden filled with consequences in the modern world. he's made it pretty obvious already that it's psychologically troublesome, and
2) because he doesn't want to have any contact with her, or anyone.
although i suspect that he'll use her as a release valve for his powers from here on out without experiencing the guilt and burden of being the only one able to use them
That girl pisses me off, why won't he just say, "It's my power, not yours!"
