Well, it’s fine if you love someone else! Don’t you have to repay the first one who once reached out a helping hand? Now it’s your turn to pay the bills. So—off you go! Toward all kinds of trials, intrigues, and secrets that Itiro’s underground keeps. And even if sometimes it’s hard to understand who is friend and who is enemy, the main thing is to endure, not retreat… and then the чужий world will become your home, the former enemy—your friend, and for your beloved you will finally stop being a stranger’s fiancée.
