In defense of author about magic. I don't think common people will be so conscious about magic even if they've got one in one day, unless they're deeply desired for power.
I'm not very well handle the bully. I would kill them all if I'm the MC, back in my day I nearly send people to hospital but they're quick to surrender so I couldn't go further.
This is what should be in many manga. They emphasize about sexual desire too much but never even touch a chick in those mangas. It is nice to see that MC not really emphasize about sexual desire and just go straight for it, feels more real this way.
When I was 19 I was just idiot who pretend to be cool and acted like everything just as planned. When I was 8 I only walk around followed people like little chick.
