Unless Karino changes they are doomed. As a broken and cynical person he needs someone who helps him rise up again not someone who confirms his beliefs. If he doesn't change and develop as you say this will have a sad/inconclusive ending.
You can tell Azusa does protect what's precious to him, for intances him taking care of his mom and telling her to be careful. He does care, it's just he's lived a life where he's seen someone close being abused and controlled. That probably is one of biggest influence on his personality, and the fact that no one cares about you if your in lower position. So his personality is composed of being selfish, and using other to get on top. You can't help but feel like he just needs someone to hold on to him, to support him- but he ended up karino. This could actually break him, and I am interested to see their development togather. Though I can't help but feel protective of Azusa from harm
