Yuri Belov

Plenty of people will dislike Yuri Belov, but the fact he's miserable and unstable is just the tip of the iceberg. As if that's not enough he's also crude, narrow-minded and tactless, but at least they're not as bad due to intertwined habits of being reflective as well.
But focus on his as this is what he's almost feared. Plenty of relationships came to a halt because of this and his demanding nature, which is far from desired, but so be it.

Fair is fair though, Yuri isn't completely rotten. He's friendly and sharing when around good friends, all considered it could be much worse.
Unfortunately his instability will probably never truly go away.
