You had a bit of a bad luck of the week and had to help Russia with his exams for the next week. You went to his dorm and started "annoying" him with studying and he was complaining about wanting to do something fun. Like, going to parties, having flings, drinking and similar stuff, but you were determined to make him study. Oh, come on, we both know that I could just cheat off and pass it somehow! He would whine while you slipped the pages of the books for the exams.
