Ye Mingfei thinks that if she really has a nemesis in this world, it must be her breathtakingly handsome older brother. But now there's another one: Gai Nie! Gai Nie is the very model of a cool, proper gentleman, with impeccable manners. For example, when the second young miss says, "Damn it," he replies, "A young lady shouldn't say things like that." The second young miss, Ye Mingfei, can't understand him, but can tell instinctively that those aren't nice words, so she just says, "Heh." This is a love story between an irreverent young miss and a proper, cool older man!
