The narrator tells us that he didn't want to choose between his brother and his sister-in-law. He wants both, and he's going to use the power of his family's influence to his advantage. He's not going to let his brother get away with not pursuing his dreams. The narrator says that he doesn't think his brother will lose to him, and that he'll never regret his decision. He also says that if you're unhappy with your grades, poor performance, or mediocre performance, you can transfer to another school and learn finance for me. He tells her to apologize for helping her brother lie to him and for helping him cheat on the entrance exam to the university. He adds that if she dares to trick him, he will double trick her back. He says he originally thought that his brother was going to leave his sister and marry a wife, but now that he seems to be worth waiting for, he wishes her all happiness. He plans to take the university entrance exam in the future to study music, and hopes to stand on stage like his sister. He thinks that they can be partners someday, since they're both so handsome. He promises that they'll be together forever, and says that they will be together for the rest of their lives.
