Help me find a novel, which seems to be the novel of the president. The woman was originally the fiancee of the man's younger brother. Later, when his younger brother disappeared, the man married instead of his younger brother. I have seen a similar narration, in which the female calls Feng Qing, the male calls, and the middle blabla. Later, the man found out how the woman was with her brother, and then what happened. Finally, the man and the woman are together ... 0.0 didn't let us see one, but the one I saw was called "One of the online games fell in love with you at first sight".
