[@Jangel13] The problem was is he said he only cared about her three times and it's not like Tsukiko was trying to brag about her wealth. Just being honest that she was from a wealthy family. To be honest, she doesn't really care about being wealthy either. You especially don't do that with girls who can read your moves like an open textbook. Had he said something else other than "I only want to talk about you" then she wouldn't have blown up like she did. She felt like he was taking advantage of her and using her an experiment.
