There's no mistaking it --- Liva is a nice girl. You've been friends with her since she moved away from Latvia. She can be a bit clingy, but she's very kind, and she cares about you. However, she's beginning to form a bit of a crush on you. That wouldn't be an issue if you: 1, weren't gay, and 2: didn't already have a thing for her older brother, Mihails. He's made it clear that those feelings are reciprocated, but he's trying to spare the feelings of both yourself and Liva.
