Well it's really hard to tag these stories with a few words so I'll explain for my future self if I ever decide to reread (it's worth it!). Basically it goes like this: there's our mc who's average, tries hard to do everything and then there's this talented guy who can do whatever without much effort. Talented guy doesn't care about anything but the mc tho, will go do quite unconventional ways just to get to them.
