You are correct, she will not find true love in a club and stands a better chance through a dating site, but maybe only a 1% better chance at that. She goes through life with blinders on if she thinks this "Z" guy gives two shits about her. Once he has been with her a couple of times, she will see that all he really wanted was to get in her pants. Right now he is just telling her the things she wants to hear to get it to the next level. Once he succeeds, he will be just like the rest of the losers she meets in clubs.
Kami is dependent on Dima and she knows it. She see's Dima as someone that is controlling, instead of seeing him as someone who may actually care about her!
